Re: SDS011 particle sensor

The power supply provides 5V, 2.4A, 12W and the SDS011 is the only device hooked to the power supply - I think that should be enough.

Hi, I want to connect a SDS011 particle sensor to a SBC-NodeMCU-ESP32 The datasheeet of SDS011 says it needs 5V power supply. But my ESP32 doesn't have 5V power supply. There is a similar setup described here . They use the VU/VIN pin of the NodeMCU to connect it to the 5V input (pin 3) of SDS011. I...

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?
