67-0462-74　［取扱停止］Smart Dust Sensor - SM-PWM-01A　114990092

特徴

• Introduction：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.
• Features：Compact size、light weight（about W59x H46x D18 mm、23g）
• PWM（pulse width modulation）output（Low pulse output）
• Enable to distinguish small particle of cigarette smoke from large particle of house dust
• 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）
• Specification：
