MHZ19 - RevSpace

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 ...
