Meet the LiV Pi: a smart kit that turns your Raspberry P into an internet connected indoor air quality monitor. LiV displays CO2, temperature, humidity, and air pressure measurements. It communicates with your mobile or desktop messaging app (such as ChatSecure). The device sends you alerts when alarm thresholds are exceeded.
LiV Pi is compatible with Raspberry Pi model 2 and B+. You can get it on Indiegogo.
