Introduction. This page is about the MH-Z19 CO 2 sensor and some experiments done with it.. This sensor gives a digital (serial) output of the CO 2 concentration in air, in parts-per-million (ppm). It uses the optical measurement principle of measuring CO 2, which should be much more accurate than the inexpensive electro-chemical sensors you can far as I know, the optical measurement ...

May 06, 2021· Hi there everyone, I’m new this this forum and fairly new to Arduino. I’m having and issue getting my MH-Z19B CO2 sensor to read in my serial monitor. I’ve tried looking at many different examples of code that others have posted in their success stories. When I open my serial monitor, all I see is that the sensor is preheating. Nothing after that. The sensor needs about 3 minutes to heat ...
