Setting up the MH-Z14A CO2 sensor with Raspberry Pi ...

17/05/2020· So I bought an an MH-Z14A sensor to get CO2-levels at home, by attaching it to a Raspberry Pi 3. Indoor CO2-levels 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; 250-400: normal outdoor air level: 400 - 1000: indoor, good airflow: 1000-2000: …

Review and Test of the MH-Z14A NDIR CO2 Sensor

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.
