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).

arduino - MH-Z19 CO2 sensor giving diferent values using ...

2016-10-09· I have a MH-Z19 CO2 sensor, according the data-sheet I can obtain PPM values via UART and PWM. The difference between both method is the limit in the CO2 concentration, where UART I should have readings between 0-5000ppm, and via PWM I should have readings between 0-2000ppm. I just wanted to know if I can have the same readings using both methods, but after tried I'm realized …
