Raspberry Pi #1 manages data collection and produces the graphs on this page using Python 3. Raspberry Pi #2 is for experimenting with a camera, Raspberry Pi #3 is for local storage and Raspberry Pi #4 is for tinkering. Temperature inside the shack is measured using a DS18B20 sensor connected to Raspberry Pi 1 and outdoor temperature is from my WS-2902C Ambient Weather station.
