This dust sensor from Waveshare features a Sharp GP2Y1010AU0F sensor, detecting fine particle larger than 0.8m in diameter. It\’s great as part of a DIY environmental sensing project. The sensor features an onboard voltage boost circuit to support a range of power supplies. Features Low power consumption Analogue voltage output – output level is linear with dust density Embedded voltage boost circuit to support a wide range of power supply Note: Pin headers not included Package Contents 1x Dust Sensor 1x XH2.54 4-pin wire Resources Product Wiki How to use with an MCU: VCC 2.5V ~ 5.0V GND GND AOUT MCU.IO (analogue output) ILED MCU.IO (module driving pin) Specifications Sensitivity : 0.5V/(100g/m3) Measurement range: 500g/m3 Power: 2.5V~5.5V Operating current : 20mA(max) Operating temperature: -10~65 Storage temperature: -20~80 Lifetime: 5 years (warranty 1 year) Dimension: 63.2mm41.3mm21.1mm Mounting holes size: 2.0mm Airhole size: 9.0mm
