Review and Test of the MH-Z14A NDIR CO2 Sensor

2018-03-09· Review and Test of the MH-Z14A NDIR CO2 Sensor 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.
