In the Embedded Systems group of our lab (CITI, INRIA / Univ. Lyon, France) we are currently designing and building a high performance ammeter dedicated to power measurements for small devices. Our prototype was presented recently at the RIOT summit in stockholm: we measure currents between 100nA and 30mA with a sampling frequency of 2Msps. Data is streamed to a PC over USB which enables long-running experiments, or just real-time visualization of data.
This prototype is directly useful to us in our research, but we think that this kind of a device could also be useful to others, so we’re putting out a survey to get some feedback. There are only a handful of questions so replying only takes a few minutes:
Please feel free to forward this message to anyone who could be interested. Thanks in advance,
