Carbon Dioxide Sensor Winsen MHZ14A – The Curious ...

+

The MHZ14A from Winsen is a relatively small size sensor which uses nondispersive infrared (NDIR) principle to detect the existence of CO2 in the air, with good selectivity, nonoxygen dependance and long life. It has builtin temperature sensor for temperature compensation and it has digital output and analog voltage output. This sensor has a UART (serial) connectivity, so it is easy to ...

06/05/2021· I got the sensor but it is crap. PWM output doesn''t work (it is either continously high or low instead of the PWM signal it should output.) and analog outputs are very inaccurate, reading starts high, over 500 ppm, sometimes more, then slowly goes down to ~280 ppm, where it stays.

17/05/2020· So I bought an an MHZ14A sensor to get CO2levels at home, by attaching it to a Raspberry Pi 3. Indoor CO2levels have pretty large impact on sleep and concentration. Usually measured in ppm (parts per million), the desired values are below 1000ppm. CO2 levels and effects source. PPM Effects; 250400: normal outdoor air level: 400 1000: indoor, good airflow: 10002000: …

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.
