Once you get these sensors, all you have to do is interface them with your Raspberry Pi and use software like Home Assistant or OpenHAB to run automations based on the sensors' readings.

The project is completely open source and based on a Raspberry Pi base station which connects to ESP32 based sensor nodes and online services to nicely present the data on a 7″ touch screen display.

We have two different options available on the 37 Sensors Starter Kit for Raspberry Pi, you can either buy the kit for $79.99 or with the Pi 3B included for $129.99.
