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.

Home water pressure sensor | Smart Home - Community

May 26, 2020· I also got a MH-Z19B CO2 meter for testing to monitor the indoor CO2 levels. The initial feeling is that it does what it should. In general I have pretty good wifi coverage with a few Unifi access points. One of the sensors is in a building some 25 meters from the house where the wifi is not that strong, but the NodeMCU has no problem with this.
