Product Description
New design cheap pm 2.5 air quality detector 4-20mA 0-5V RS485
Modbus output environment dust sensor outdoor air quality sensor
BGT-PM2520 Air quality sensor Detect the concentration of particulate matter with diameter less than
2.5 microns and less than 10 microns in the air.The principle of
laser scattering is adopted, that is, the laser is irradiated on
the suspended particulate matter in the air to generate scattering,
and the scattered light is received by the detector at a certain
Angle,and the generated photocurrent is amplified to obtain a
corresponding curve of the electrical signal and the particulate
matter.After data collection by microprocessor, the particle mass
with different particle size per unit volume is obtained through a
series of algorithms.
