Project power measurement

sftwrngnr

I've been thinking about how to measure the power usage of this project, since that is one of the design requirements, and I've decided that what I'm going to do is utilize a separate measurement and logging circuit so that the actual process of measuring the current draw isn't a parasitic draw.  The simplest solution I can come up with is to just have an arduino with a current and voltage measurement circuit attached to it log the data and report it upstream to the website separately.  As I read it, the parameters of the design challenge don't specify that the current draw must be included in the IOT data stream that is explicitly sent up, but do clearly state the requirement for the power measurement to be captured.  The way I see it, provided that I have a mechanism to send the power measurement datastream up to the site, I'm meeting the requirements of the design challenge.  Alternatively, I could have the SI Labs embedded processor pull the data from the Arduino periodically and transmit it to the other device en masse.

 

Any thoughts/Comments/Flogging?
