Apr 27, 2021· MH-Z14A CO2 Sensor. For our Corona CO2 sensor, we use the MH-Z14A that has an operation voltage between and Therefore, the CO2 sensor can run on all Arduino microcontroller with an operation voltage of 5V. For ESP8266 and ESP32 microcontroller with an operation voltage of , we have to use the 5V output from the USB connection.
Mar 09, 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.
