MH-Z19 carbon dioxide gas sensor (hereinafter referred to as the sensor) is a generic type, small sensors, using non dispersive infrared (NDIR) principle to detect the air in the presence of CO2, with good selectivity and no oxygen dependence and long service life. Built in temperature compensation, with digital output and waveform output, easy to […]
Jun 05, 2016 · NDIR (nondispersive infrared) CO2 sensor is the most common type of sensor used to measure CO2, which has good precision and low power consumption. Prices are very various. MH-Z19 sensor has good characteristics and great price, so I decided to buy this one. MH-Z19 sensor technical parameters: Working voltage. 4.5 V ~ 5.5V DC.

CO2 sensor. There are numerous CO2 sensors available, a non-exhaustive follows here: NetAtmo Home Coach (100 EUR) - measures VOC (volatile organic compounds) as proxy for CO2, not CO2 directly. It's also relatively expensive. S8 SenseAir - similar to MH-Z19, but more expensive. MH-Z14 - appears to be an older version of MH-Z19.

MH-Z19 CO2 Sensor. The MH-Z19 is a small non-dispersive 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 ...
Recently finished my first library for the MH-Z19 series CO2 sensor (brings new stuff) Hey all, I recently finished my first library a few days back for the MH-Z19 series CO2 sensors (Z14 is untested - does it work?). It supports both hardware/software serial and Arduino based boards, including the ESP32. My poor sensor has under-gone a beating ...
