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
  • Use it in your garage: gasoline and diesel engines give off large amounts of CO2
  • Use it in the conference room at work

LiV measures CO2, temperature, humidity and air pressure.

LiV is open source. All LiV Pi hardware and software files are here.
