Dust Sensor Module DSM501B Description 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 DSM501B Type: DSM501A : 2mm pitch connector type (20010WR-05). DSM501B : 2.5mm pitch connector type (S5B-EH). Dust Sensor Module DSM501B Electrical characteristics: Supply voltage: DC5V +/- 10% Power consumption: 90mA Operating temperature range: -10~ +65'C Operating humidity range: 95%RH or less (without dew condensation) Recommend storage condition: -20~ +80'C Dimension: W59 * H45 * D20 (mm) Detectable particle size: approx. 1um (minimum) Detectable range of concentration: 0 ~ 1.4mg/m3 Output signal: PWM (pulse width modulation) Time for stabilization: 1 minute after power turned on Sensor characteristics: To be maintained in between the upper limit and lower limit of the standard dust sensor unit Dust Sensor Module DSM501B Features: * PWM output * Easy installation * Single power supply * Compact size and lightweight Dust Sensor Module DSM501B Application: * Ventilator etc * Air conditioner * Air quality monitor * Air cleaner or Air purifier
