MH-Z14a reading below 400ppm while outside …

17-06-2021· I have a project, that among other things measures CO2 levels using this arduino mega 2560 R3 and an MH-Z14a. 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.

MH-Z14A CO2 Meter Tutorial with Arduino, …

27-04-2021· Using the PWM interface of the MH-Z14A with an Arduino microcontroller (green line) The PWM interface is the only one that has no outliers and can therefore be used for our CO2 alarm. Most of the time the PWM values are also validated by the CO2 concentration from the UART interface.

Review and Test of the MH-Z14A NDIR CO2 …

09-03-2018· The MH-Z14A measures CO2 concentrations using absorption of infra-red 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.
