Product Description:
ZH03B laser Dust Sensor For Air Purifier Fresh Air System
Features:
ZH03B Laser dust sensor (PM2.5 sensor) is a universal, miniaturized module. The Mie scattering principle is used to detect the dust particles in the air, which has good consistency and stability. With serial output and PWM output, easy to use. Small size, easy to integrate.
Detection particle size range 0.3-10μm
Effective measuring range 0-1000μg/m3;
Detection interval 1s
PM2.5
Detection accuracy 0-100 μg/m3: ±15μg/m3; 101-1000 μg/m3: ±15% reading
