I am thinking of buying Grove - Dust Sensor (PPD42NS)

Grove is a modulated, ready-to-use tool set.
Much like Lego, it takes a building block approach to assembling electronics.

I am thinking of buying Grove - Dust Sensor (PPD42NS). I want to connect it directly to nodemcu . I am trying to find the wiring schematics and code that works for nodemcu. Is it compatible? Please help

Hi there~

The grove dust sensor works on 5V, and node mcu works on 3.3v. It is NOT compatible. 

For the cable connection,  For the wiring, you can connect the signal to any digital pins. thanks. 

Thanks
