Dust Sensor Module: DSM501 series detects the level of indoor airborne dust, particles, and pollen, and ideal for use in stand-alone air cleaner or IAQ monitor. PWM output of the sensor can be directly connected to μ-com to control fan speed or ventilation and also to display the level of particles. Detectable size of particle is limited to minimum 0.7 μm, and the application for smoke or fire alarm is prohibited.
Dust Sensor Module DSM501BType:
DSM501A : 2mm pitch connector type (20010WR-05).
DSM501B : 2.5mm pitch connector type (S5B-EH).
