Meet the WattMote (Moteino based Tweet-A-Watt) #piday #raspberrypi @Raspberry_Pi

WattMote

From LowPowerLab, via a tip from Kevin Groce!

I assembled my Moteino circuit inside the KillAWatt. Everything fits very nicely and the LED blinks every ~2 seconds, and data finds its way to my RaspberryPi where EmonCMS records and graphs it nicely. At the last minute I found a leftover TMP36 analog temperature sensor that I had around, and thought – why not add it to the Moteino and report temperature along with power readings?

I feared the TMP36 sensor alone would draw too much power (even an extra constant 2mA is too much for my KAW!). But it turns out it’s a very low power sensor (just 0.05mA). Since Adafruit has a very nice demo and code for TMP36, I won’t replicate the details here, you can check them out at Adafruit’s learning system.

Now I’m getting temperature, voltage and current waveform readings from my KAW.
