Testing the MH-Z19 Infrared CO2 Sensor Module • Circuits

· Introduction: In this article we will do a simple functional test of the MH-Z19 CO 2 sensor by connecting it to a raspberry pi 3 UART and run a simple datalogger python program which prints results to the screen and stores results in a csv formatted file. The file can later be imported to matlab or excel for further analysis or just plot a graph of the collected data.

MH-Z19 CO_2 and Temperature Sensor — ESPHome

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).
