MH-Z14A CO2 Meter Tutorial with Arduino, ESP8266 or ESP32

Apr 27, 2021 · For our Corona CO2 sensor, we use the MH-Z14A that has an operation voltage between 4.5V and 5.5V. 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 3.3V, we have to use the 5V output from the USB connection.
