This module is a dust sensor capable of detecting more than one micron of dust particles.
It has two types of output: high-level 4V signal output for a clean, low-level environment 0.7V for a particle-laden environment.
Its power supply is 5VDC and the particle detection range has a maximum at 8000 units per 283ml.
