MHZ19 RevSpace

This page is about the MHZ19 CO 2 sensor and some experiments done with it. This sensor gives a digital (serial) output of the CO 2 concentration in air, in partspermillion (ppm). It uses the optical measurement principle of measuring CO 2, which should be much more accurate than the inexpensive electrochemical sensors you can find.

MHZ19 CO2 Sensor Home Assistant

The MHZ19 is a small nondispersive infrared sensor that can measure CO2 level. High CO2 levels can lead to drowsiness, poor concentration, loss of attention or increased heart rate. The CO2 level outside is around 400ppm, but inside levels can reach between 1000 and 5000 ppm. High CO2 levels indicate that you should increase ventilation.
