Abstract 
In this talk, I will introduce the need for energy measurements for embedded devices and show how they may be performed accurately and for very low cost using a combination of offthe shelf parts and a wide range of target embedded systems. I will cover the basic physics of energy measurement and go on to display designs for energy measurement kits, including the power sensing boards recently developed as part of the MAGEEC research project.

a and include some of the sort of chemical because that it's in the 2nd cope in which
00:12
the set of all the the the end of the of the of the of the of the of the
00:28
in the data and that the mean and so it kind of thing in
00:43
the and the and the and the and the other
00:58
and began to but it it should be a and the human
01:13
and the last thing the fact that we have not yet at
01:29
and so the end or in the form of and so on and so on and so on
01:48
and took it and at the end of each atom important
02:04
what is that that you would want to do a lot of interest in the world and
02:14
it's a little difficult to this and the so this thing it would have to be in
02:28
the we can begin to make it clear that it's interest of because of the follows which send but they this point could contribute
02:45
to the to that and I do not have joined along with long the short time so you would perform
03:01
the OECD the there were no tunable with the because they didn't they still do the
03:14
same thing with each that's what it is just going to commit to conform to the unique to the to the
03:28
we tend to think about it but it would be interesting to see it and think about it because we have the the the the the in the of
03:45
it can traffic because of the involved in the and and this is also visible by the work
03:59
of evolution of the pitch I think I so the price
04:15
of the book and the book
04:18
about the state and 1 example is the use of the measures the whole set of smaller basis through necessary a little life the the right at the end of the world and I was in the ground truth about the middle part of the bacteria we will show I the look and things like with the later words of the and the room and he and of pretty so that so that they can be written
05:07
like this this get a room in the year of the tree and with
05:17
the in before and to
05:26
you whom you could that
05:29
yet no the picture this is
05:32
the end of the day and the lack of a better
05:45
living through the mean of the
05:47
the values universe was in a manner that is useful for various reasons through and then we could also use this in the on the other hand on and that's the only thing you need to have of the bad and myself so small that the bases of the use of all of the things that most of the data and so you might devices that and and the the only thing that brittle make the project there in the and the meaning of the phrase in in the and so is all you know little about 1 of the and that you our the ladies it's all about misery out the pen and how will you can I was on the on the moon and energies are measured on the basis of the of the of the conservation yeah well what you had and that's the reason and the idea of of the of the of
07:12
and that this what will make the most of the work of love to find the optimum the back the summer and this process very when it is
07:26
1 and then you have to to do and so that's the point like the more you can think this is that the use of the cost the videos to welcome you the 0 is was 1 of my research and what they were not very big unless you use the US programs and they have things you can do this in the fact was out in that way will your house and the and also using the house of many of the things we have and this is the reason that the relations of the back of the book is by using you of that of the use of this design all and this was this was really holes at at the rear of the of and after that I will let you know that the real world you that you have to look at it so you know you have a rule that was used in this reduces the number of times and so you have a house that's and this is what I have existed in the of life and the more of in the the cost of 1 of them was so the reason we're out of the house in the so those who do experience and having which is
09:21
the is the 1 that was and and that relates to your use of this so this is the relation that and and the other is that way you have to have in in a product
09:41
that the use use of these varieties and what the the reason and that was all the things that have been used In this
09:58
poster and this is the mass of the state of the art of the University of I was reading
10:08
about the end of the world and this a very useful later you want to see that the of the meaning that both users and in the 1 of most of of this in so you know I was looking
10:31
at what he actually did this it was a prominent politicians of time and money will involve the reason the gap between North and as the new measurements the rest the women
10:47
of it in the game that the amazing thing is in so you get to work In this you get this idea yet he is the enhancement of the movement of the the measurements in a set of sensors and most of in the right you can also think of only it as a process which is really there an ion volume but there is and is how to of the power you have everything you so it is in
11:33
the metric the ones mentioned about the landing site in these mice and you know you have the right to you and you they you savings I love I have been used
11:46
for years and then you know that it's very useful to the user the user and the with their own community and the use of the 1st half of the good in will the problem in computer science which is now in use in many applications the is going to be used for you have been stationed was so much on any level but we both know that this is different from that in the sense that they is had to buy them to do in the name of the student with the press and so sometimes you want to and if this is the sample mean so that when actually it wasn't of thank you and you can live on the rest of the gradient then the however is to think of the information the value of the then you will return to you and that is easy to measure what that's we so that's what we do a few the use 1 of the things that you want to do so we have to go to the middle of a very large in the
13:32
hands of the people in the presence of a and
13:43
that so that this will lead to what is it that the but also in the power system is currently resident on the left side of this system it's a hybrid systems
13:58
and now I'm not find that this is the the user that I don't have that current 1 thing I know there are many of the problem that you would use this change in the training data that are you know and so that means that the resistance of the restaurant you want to know what this is and so on and so on and it was also the 1st time you see
14:38
a theory is a set of items of all the face of current this is this is how high and this is the end of the
14:50
duties of your mind you will get right this is what you find know so so that the person is on the other side of the current state of the art in and in the field choice and you can use these things it's not a very and I and
15:27
through magnetometer of this but we remember this the 1st and say these things the the of the energy of those over an area of knowledge is used to being use of some of them more of the the whole and of the we use these elements and and the so this
16:01
is 1 of of the most spectacular is similar to the survivor
16:07
error the use of the user knows is generally all of you that you In so we want to test the you and and the idea is that this will be able to use this knowledge to overcome this and on there has been a lot of the music fell dramatically in past the ends of the right of the face of the and usually you know have 1 or more all of these in the
16:50
sense that you don't want to do here is that on the episode later
16:58
on in this and the only thing you know what I'm really about certain muscle these are all the best in light of In the authorities will depend on the of this is the 1st what is so that means that you have in the 2 types of that then
17:31
you do you think happens here is that there is a sense of the descending into the grave of the
17:43
treaty in and so when I find that 1 that lasts I heard the right this the internet is seen on the in and out of the reach of our universe of so we have all the across this child and had this and is how not always but there is 1 reason to treat each and the out of the so so that 1 can do as the and we after you
18:30
the and reason this is the knowledge and the 1 the that so when it came to formalize this and on the structure of the day of the year is over and the
18:58
reality of values on the on the on the on the not in it is a lot of
19:10
ones that has to get get this this is certainly 1 of the and so the rate said this is sign on the wall of the of the practice of unrelated the to the center
19:29
so that you can think of the universe and the right the
19:41
example of that the 1 side find another 1 the things that we in the so the most things
19:54
and changes so although in the form of the conservation and starts at the level of in the of in so that's being used in the and that the fact that you need to be seen in
20:21
the and then the use of this device the left and this is and you have a range of this is is the way that you get and the change of the protons and the and so when I haven't yet figured out the necessary and that is a lot of different so the theory is that it you know the and it has a view of what influences the rate of the user has to pass you change
21:04
dollars to what was the last part of the of the of
21:10
the of the theory of why is it so that it what we in this I
21:21
and that this is the the not so
21:30
by the time the main part of this will be very so the
21:38
goal is the same thing the by the way will be the final only heroes that we see on the rest of the of the really you like those that just to have this letter was really a year all the things that function and so on but they won't say the use of them on the built into a very large number of people in the that and made using the the you know the the highlevel diagram a law
22:25
of the processes on the other side and on the the pieces so you might in
22:38
the same year as the mean in and the idea of what the resolution FIL responsible to the and they have that now the thing about the policy in the view about the quality of the the of the of the that is the key to the other side of the that the ADC will most of the growth and so on and so what the the people you have to do is use it that's that's all you get out of it in in a way that each of the of the of the get things that you don't want to admit it so the sum of the you know the the the the concept of the and all other of each of the time
24:09
that it was the 1st of all season in the hands of the house on me the following 3
24:20
of you you now we need to be simple to bring them in line with in this in the philosophical obtained by using this analysis we prove that I read in the room and the way use there will be as the concentration of all of the brain to have 0 labels the labeling that will get you can work on any reading right so that's the so that the them because of the use of was is wrong with this not is you
25:14
get a curve that is the kind of and so you have to have the we start by the think will actually and
25:28
kernels and also of it we also find that the like the the this this is the self and so you have to remember this results over the last the this is because you have to make use of them you can look at all of the you know that the
25:59
the the the
26:04
and
26:22
a so that both
26:29
the Government figure in modern and innovative on so
26:35
I have all these little machines UTI in closed image of the and they all the animals this means that the use of the title of a book that is called the lactase and so we do have a lot of the
26:57
people these people in order to transform the current development in because of the the you know and I will
27:09
do is a little less than the distance across the line of the
27:15
Americas lacked this enables 1 to the other factory and populations in in this idea is small enough to be usable in the middle of but if you go out of the group and you make a difference because you have to pull and the test this article is part of the this will hit the line minus the life of the so you see that there are so called free will the director of the in the
28:01
form of this work is that this is a list of what about the time the the that would and also the the right
28:16
kind of you know with your reduces the response time of the next word in the reality small you get rid of all the rest of the time his so he so there have been a lot of the of
28:41
the of the survival of the most by the the best 1 the point is the you know so and you would think that the
28:53
role of of life in the use of exactly the same way as the fall off in the brain which is the 1 thing on the right what's in the class of convex and so this break the rules of the small so it'd be desirable in in the in part of greater the the funny thing was that we wanted to maximize the use you know all the solution the more points in the region so what we did is we
29:42
on the animal may want to use the just for the original wheels of the of the the sales of the opposite of what goes into the the exactly the did
30:06
so that is how you will about the right of well that's so the years unions of the university
30:16
that you use 1 of the lot of the very available jealous you will accept this provisions on the 1st of the year the UK which gives you a
30:36
new set you have be on the that would be the next thing years I was in the form of those areas you know you want it to the middle of the field this is what we densities with a lot of the meaning of the name of it that can we think valuable tool this is that small was the sum of the that is on your not that was a form of what would you you use that was made you want to make use of all the energy of writing a letter
31:30
of the law and so the next line of each of the current sentence I designed all the creation of an application of Bayesian reasoning with the you know the maximum of the Uranus and most is of the this and I'm 1 of all the mean of
31:53
the of course you and you do all this is that the the devices have the thank you say what is fast is that that was in the in the very low by the because there of Part to and it goes to the 1 that means is that you call this major accuracy the the the the the the the the I and the result of this this talk the little 1 is the would be the this last about this of disease and it is
32:54
measured using the community of so this kind of households which is in the hands and so we to talk about about the people in that they would be the sum of this this is unit of the this is because that was the thrust the United Nations you with this so the rate of this kind of what people do is have a problem and the very this is the same same in all of the time you know what you get a chance to talk to you later in the year the the solution to this problem that we have to look at what I get if you would like to do is just to this and that so the the the and so the always I that 1 of the things that we would have had its roots in the music so the total in the use of of the same thing for the university you win that you see the the 1st thing we said was that of the of the of the site a and I was looking at the end of culture where you on the use of of it it will measure the power you did with the interval deliveries of the or anything because you will win the In the end of the year after correlation of features in the game the and that's the
35:17
way it is with you but this would have been in in 2 the idea is that we have a place in the park and has builtin error
35:31
because we really did want usually you find the 2 it is and so you you have there and that's almost all all of the things that could be taken value of the measurement you know is this sort of leads you have you know that all the time and you know and you need to let these users to the end of the year and there is also a bit of the other than by sampling problems and that I want wanted buy a used all parts of
36:19
the this is the result of
36:23
the this so this this is the color of the book that is 0 1 was once in while 1 of the things year you're so it is and the blue you got it you got lot this going on that gives all this side of data and you have to go on from there have been places and they have been raised the the Soviet Union at all it the university is common to all as you know it so the lowest memory we can be reversed versus alignments that will be the ones that guy and he was born in of the involved in the in the and in this case this absolutely so the the columns of the original vector there a this is what this is saying is that have always has told that the by the loss and you can measure the you know the trees in the engines of the resources and signed by the inverse of the system so in the long view of the in the in the and yes so associations and we have to do that is to the the idea that the things that we use in the analysis of the newly at the time by the user that some of the limitations of the the of right and will have to connecting
38:46
the 2 and we will have on on the use of the solution of this year on the basis of is and adding the 2 of
38:59
Lewis united we want to
39:04
have a lot of 1 is 1 of those lines but she did not like it but
39:10
this is the the the the man I was the 1 that is 1 of the ways in the multimedia and here you can see the properties of the 1st mind and that new was happens at the white doesn't have the staff and
39:38
and the sum of the year that was possible only in the case of what it would you the
39:50
that you want to do that with the of solution of the the workers
39:58
and the the and 2 of most of my yeah think that 1 small devices from the cost like it's good to see that small the questions that this was a bit of a and the outside of the capital would have these things here variables within the rise the the difference a close you and so do you want me to and what it is that there
40:39
will be a part of and quite a ways in a revival of 1 mole restful that is really a
40:54
so this representation is just a change
40:56
of venue with regulated and you get what it was the 1st flight of and in so
41:08
you get of it follows that the world matter and the images well we drop people that the of the and the
41:20
diversity as he's not with labels the person with the work we are in the same condition you would you would you 1 more
41:32
forms this invention in relation to juggle good they actually have the system working in meaning and those who has a in
41:49
this regulation has to be made In this work we consider the the
41:57
environment of the 1 that comes to
42:01
violating that search and the decision in the indices of another really good and by how this like all the and those that was set to and was like the with the of the In the last time the the size of the the long of use all the only and the and then you get the you will you know that this is all although the final decision we I
42:50
think you know and and and so I want you to
43:06
find will act as 1 of the reasons is the most widely and on the other side the have of the of the whole things that you know this is the nite of hospital that when you part of the scene and
43:34
the last thing we have to do
43:37
so in a way that is the in is what I have existed and possibilities of the and we also have to realize the what this single and will because they take time
43:56
on that and 1 of the things you interchangeable only in the last of them and the models you know I think that the now where where it was 1 of the things of use American you so that the rate was caused by a change of scene but all this is my 1st so this is the 1 that would be the 1 in the world that you will see that for some time only using the and that means the theory that the only
44:37
possible because of the values what happens is that is all you I thank you don't lose the reason that the variance of each of the 1st 1 you know a series of studies is the 1 want that 1 any more interested so you have to have a person who lives in this part of the the of so the setting was measured using the method of images of the the of to know so that reminds you of the modified variances and images on your phone and you know what that means you
45:34
have to use a very new represent this a we have a universal because of the the only thing that really say that through the know that it is in the moment that it would be a lot of was in and so was this was the thing will the fundamental very rapidly you'll never
46:15
get out is that the resolution said is this line my some of this from the the the United States Navy have this so that all of these I wonder if that is
46:33
true and by the way of Tanglewood side with the the and and we will be lost
46:44
and the result is going to be a so that's also where we a lot of work to theory on the I think it was situations and that you may have the ability to times this is the point is you
47:03
need a lot easier to buy in the of the of the of the of the of the region there is still a very old the lines in the red part the whole picture like that in the OK and in the text of the and and also this is on the will in the losers she
47:36
of the people in the world you want to correspond to the user and the next the muscle and the land of a and
47:55
that sort of thing you need to find out the size of the model and the provision of the and you will use the following verses that reduces the use of in the the so I think without this to and says the is very useful
48:23
to do this say is like that of the 3 of them because they have more that what
48:30
is thing that in the in the middle of the day the with and maintenance of the level of breaking track so the 1 in the the language of the family
