Had a look at sample code of groove dust sensor

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

Had a look at sample code of groove dust sensor. The concentration output in the end is of PM 1.0 or PM 2.5. I am looking for a sensor module that can give me concentration of pm 2.5

Hi there,

Grove-Dust sensor uses counting method to measure dust concentration, not weighing method, and the unit is pcs/L or pcs/0.01cf. It measures PM whose size is around 1 micro meter
or larger.
