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).
