Review and Test of the MHZ14A NDIR CO2 Sensor

09/03/2018· The MHZ14A measures CO2 concentrations using absorption of infrared light. These devices are available on eBay, Amazon and other places from about 20. Ignore the capacitor across the power pins this was a failed attempt by me to improve the reliability of the analog outputs. My initial impressions of the module were pretty favourable.


MHZ14a reading below 400ppm while outside after ... Arduino

17/06/2021· I have a project, that among other things measures CO2 levels using this arduino mega 2560 R3 and an MHZ14a. I''ve attempted calibrating the sensor by letting it run outdoors for >24hours and also by sending the zero point calibration command after 30min. Neither seem to work as I still read below 400ppm (between 140 and 200ppm) outdoors.
