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

20210617· 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.

MHZ14 / MHZ19 CO2 sensor Let''s Control It

20160727· Then opened from the Arduino IDE, which also loaded the other .ino files in the tabs. Compiled it for Wemos D1 Mini and flashed it. Then configured the device: But the ppm stays zero all the time: I don''t know what i am doing wrong. The MHZ19 is working fine with a different sketch. Pin ''Tx'' from CO2 is connected to ''D5'' on Wemos

Review and Test of the MHZ14A NDIR CO2 Sensor

20180309· 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.
