Man, if you are already running with a raspberry pi you should just grab an extra sd card, drop the latest raspbian on there and give mycodo a try. Installation is simple, and it supports all that beautiful Atlas Scientific stuff right out the gate. He’s even built in a calibration function for the probes already. As long as you know what GPIO pins you’ve connected to setup is super simple. If you’ve already got things wired to the pi you’ll be switched over in no time!
