How to operate MG811 CO2 Sensor on ESP32 - ESP32 Forum

Dec 30, 2020 · Re: How to operate MG811 CO2 Sensor on ESP32. Postby ESP_Jan » Wed Dec 30, 2020 1:20 pm. Hi os3n6c, based on the specifications the MG811 sensor requires 6.0V ± 0.1V @200mA for its operation. You will need to have a 6V power supply for this sensor or a voltage regulator. Feel free to post any follow-up questions.

Arduino | Adafruit SCD-30 - NDIR CO2 Temperature and ...

Jun 23, 2021 · The SCD-30 is an NDIR sensor, which is a 'true' CO2 sensor, that will tell you the CO2 PPM (parts-per-million) composition of ambient air. Unlike the SGP30, this sensor isn't approximating it from VOC gas concentration - it really is measuring the CO2 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific ...
