Description

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)

介紹:

這是通過使用光感測方法檢測空氣中的塵埃粒子濃度的灰塵傳感器。一個紅外發光二極管(IR LED)和一個光傳感器被光學佈置在設備中。光傳感器檢測反射的IR LED的光通過在空氣中的灰塵顆粒。

智能灰塵傳感器可以檢測到小顆粒如香煙煙霧和它可以通過信號輸出脈衝模式分辨的小顆粒像大房子的灰塵煙霧。

特徵:

  • 體積小,重量輕(約W59x H46x D18毫米,23克)
  • PWM(脈衝寬度調製)輸出(低脈衝輸出)
  • 啟用於香煙煙霧中的小顆粒從大顆粒塵區分
  • 粉塵傳感器由加熱器電阻恆強制空氣對流
  • 無鉛並符合ROHS指令標準
  • 最小粒度可以在1μm的被檢測
  • (屋塵大小:平均20微米,黃塵大小:平均20um的,香煙灰塵大小:平均1微米)
