MH-Z14a reading below 400ppm while outside after ... - Arduino

2021-06-17· 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. Here's a "working" slice of the code that I'm hav...

Anyone with a MH-Z14? - Sensors - Arduino Forum

2021-05-06· Anyone with a MH-Z14? eXistenZ February 23, 2016, 5:23pm #1. My MH-Z14 CO2 sensor seems unreliable. Does anyone have any experience with these things? The PWM output is easy to convert to ppm, but the dutycycle stays the same, more or less. Am I the first person to be ripped off by the chinese selling me cheap junk?
