Introduction: LiV Pi - DIY Indoor Air Quality Monitor
LiV Pi is a sensor expansion board that turns your Raspberry Pi into a modern indoor air quality monitoring device.
- Use it in your living room
- Use it to test the air quality in your bedroom
- Use in in your greenhouse to measure CO2 levels: higher levels of CO2 make plants grow bigger and faster
