Testing the MH-Z19 Infrared CO2 Sensor Module • Circuits

Jul 11, 2017· 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.
