Dust sensor DSM**1A for IAQ monitor
Dust Sensor Module: DSM**1 series detects the level of indoor airborne dust, particles, and pollen, and ideal for use in standalone air cleaner or IAQ monitor. PWM output of the sensor can be directly connected to μcom 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.
