I am soon buying a tank to house some turtles. I would like to project a system where my pi monitors the air and water temperature via DS18B20 waterproof sensors.
Ideally I would like the pi to email me a warning stating when either of the sensors are outside of set range (25-29 degrees Celsius.)
I have read http://www.cl.cam.ac.uk/freshers/raspbe ... mperature/ and believe this would work but I need your help working with multiple single wire sensors and with making the pi email when required.
All assistance and comments welcomed.
