CO2 sensor MH-Z19 -

The MH-Z19 is a sensor that uses the non-dispersed infrared principle to detect CO2 in the air. It has built-in temperature compensation and high sensitivity to gas detection, and therefore has extremely accurate readings, and its outputs are on UART and PWM. It consumes little electricity and has a long service life. • Model: MH-Z19• Voltage: - • Response time: less than 60s ...

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 ...
