Testing the MH-Z19 Infrared CO2 Sensor Module

In this article we will do a simple functional test of the MH-Z19 CO 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. If you want to use a PC or Raspberry Pi ...
