No any data

[Zzar61]

Hi, I have SDS011 sensor but can't measure anything. Once I choose right COM port and press connect button nothing happened. It is connected but no any data - please see screenshot below. I am sure that sensor works OK because on RP3 all is OK. I tried on Windows 7 and Windows 10 but it's the same. Do you maybe have any suggestion? Many thanks.

Is the driver installed and working correctly? I have this in my device manager

and if I connect to the COM3 in putty (windows terminal emulater) using serial mode (at 9600 baud rate possibly incorrectly ) it shows this garbage

(I at least know it's saying something and is connected).

Mine (a Nova SDS011) works but is misidentified as an SDS021

Not sure there, but reminds me of an old situation where you have to forcefully uninstall those drivers(with the button in the middle window) then install the ones from the readme before rebooting.
Alternatively and probably first, you should try choosing update driver, then you have to point to the one you downloaded (and possibly extracted) and if it lets you then you'll be using the correct one.
Better still google installing ch340 windows10 and you'll see windows10 is an asshat, but this seems promising https://forum.arduino.cc/index.php?topic=397368.msg3440837#msg3440837

Found the problem, my CH340 came with a premade cable for the SDS011 but the cable had been made incorrectly. I made a new cable and all is working! Thanks for the help!
