The PM2.5 sensor uses laser scattering theory to detect atmospheric PM2.5. It features high-precision detection, rapid response and steady operation, with minimal errors. The sensor can detect a range of PM1.0 to PM10.
PM2.5 refers to atmospheric particulate matter with a diameter less than or equal to 2.5 micrometers. The longer it is suspended in the air, the higher its concentration will be, representing increasingly severe air pollution and harmfulness to human health.
This module interface is blue, indicating the dual-digital interface needs to be connected to the blue interface on the mainboard.
