[edr1924]

I'm busy installing the fantastic new AQMIII but the SDS011 sensor refuses to cooperate even after putting it for a full hour in a microwave.

Anyways, the SDS011 does work on it's own with a generic library so I know it's not broken.

I do use the right software: IDE 1.8.15 and ESP32 1.06
Board selected in the IDE: LOLIN 32

The ESP32 is connected to the USB and a separate 5V power supply
(so I don't understand the brownout message)

I noticed that the fan of the SDS011 is not running and the LED only blinks ever ~8 sec.
