Ceiling fan with CO2 sensor

Ceiling fans seem to be an oft-misunderstood or overlooked household appliance. As such, they seem to have missed a lot of the IoT wave.

There’s a lot more to a ceiling fan than maintaining a comfortable temperature, as developer EJ demonstrates with this smarter ceiling fan build.

The entire build is based on a Raspberry Pi Zero, and nothing needed to be changed about the ceiling fan itself for this added functionality because it already included a radio-based remote control.
