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.

I do have a 5V Power supply now.
The connections from SDS011 are:

not connected
not connected
5V -> + of 5V Powert Supply
not connected
GND -> - of 5V Power Supply
R -> RX0 (ESP32)
T -> TX0 (ESP32)

I have MicroPython v1.14 installed on ESP32.
If I start both - the ESP32 and the connected SDS011 ...

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 ...

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?
