Smart Dust Sensor - SM-PWM-01C

This is a dust sensor that detects the dust particle concentration in air by using optical sensing method. An infrared light emitting diode (IR LED) and a photo-sensor are optically arranged in the device. The photo-sensor detects the reflected IR LED light by dust particles in air.

The SMART Dust Sensor can detect the small particles like cigarette smoke and it can distinguish small particles like smoke from large house dust by pulse pattern of signal output.

Kit includes interface cable.

Note: SM-PWM-01A dust sensor cannot count particles or measure quantitatively; the size is only for reference

Features:

• Compact size, light weight
• PWM (pulse width modulation) output (Low pulse output)
• Enable to distinguish small particle of cigarette smoke from large particle of house dust
• The low pulse width is proportional to particle size and concentration
• Constant forced air convection flow by heater resister in dust sensor
• Lead free and ROHS directive compliant
• Minimum particle size can be detected over 1μm (House dust size: avg 20μm, yellow dust size: avg 20um, cigarette dust size: avg 1μm)
