I have tested the SDS011 with the manufacturers software and the USB to COM port adaptor that came with it and it works fine, so I know the sensor is ok.
I assume that I need to wire it up as follows.
AQM SDS011
SET TXD
TX RXD
GND GND
5V 5V
Hello Andy,
I don't have SDS011, but I'd try to switch the wires TX and SET ...
Good luck!
