MH Z14A CO2.

Review and Test of the MHZ14A NDIR CO2 Sensor

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.
