How to operate MG811 CO2 Sensor on ESP32

Hello,
I have a
MG811 CO2 Sensor and want to use it with an ESP32. The MG811 needs 6V Power supply. I guess the
ESP32 only supports 3.3V
Is it possible to operate the MG811 with less than 6V e.g. 3.3V
If not, is there any way to get 6V out of the ESP32?

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

Olá,
existe uma biblioeca para trabalhar com esse sensor, no Arduino IDE?
Obrigada.
