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 ...

MH-Z19 CO_2 and Temperature Sensor — ESPHome

MH-Z19 CO_2 and Temperature Sensor. ¶ As the communication with the MH-Z19 is done using UART, you need to have an UART bus in your configuration with the rx_pin connected to the TX pin of the MH-Z19 and the tx_pin connected to the RX Pin of the MH-Z19 (it’s switched because the TX/RX labels are from the perspective of the MH-Z19).

MH-Z19 & MH-Z19B

Auto Calibration: The MH-Z19 is a sensor that is designed to be powered on and rarely turned off. The sensor calibrates over time (if autocalibration is on) using the lowest CO2 observed in the prior 24 hours). After 3 weeks, a value is stored with an accuracy rating, this can be requested using getAccuracy(). ABC must be disabled each day, however this is handled by the library. Calibration ...
