MH-Z19B I2C

Tindie Blog | A CO2 Sensor for ESPHome

Aug 13, 2020· The MHZ19B is a pretty neat sensor. It uses nondispersive infrared to detect the concentration of CO2 in the air. This makes it pretty immune to the percentage of oxygen in the air, and with no moving parts or chemical sensor elements it should have a fairly long lifespan. It can detect concentrations up to 5000 ppm, at which point most ...
