Arduino Current Sensing

Here's a current-sensing module from Sparkfun.  It's non-invasive, clamping around the wire carrying the current you wish to measure. I'm planning to use it to watch a particular appliance and see when it's on and off.

My initial plans are to attach it to an ESP8266 (Huzzah breakout), upload the measured current to thingspeak via a local wifi, and watch it from there.

Example apps:
(example 1)
(example 2)
