From Waveshare Wiki
Overview
- Onboard sharp GP2Y1010AU0F, detecting fine particles larger than 0.8μm in diameter, even like cigarette smoke.
- Low power consumption, analog voltage output, the output level is linear with dust density.
- Embedded voltage boost circuit to support a wide range of power supplies.
Specifications
- Sensitivity : 0.5V/(100μg/m3)
- Measurement range: 500μg/m3
- Power: 2.5V~5.5V
- Operating current : 20mA(max)
- Operating temperature: -10℃~65℃
- Storage temperature: -20℃~80℃
- Lifetime: 5 years
- Dimension : 63.2mm × 41.3mm × 21.1mm
- Mounting holes size: 2.0mm
- Air hole size: 9.0mm
Sensor Characteristics
The output voltage of the module is proportional to dust density in the range of 0 to 0.5mg/m3.
Control principle
- Enable the internal infrared emitting diode by setting the pin ILED to HIGH.
- Wait 0.28ms, then the external controller starts to sample the voltage from the pin AOUT of the module. Notes that the output wave will take 0.28ms to reach steady-state after the internal infrared emitting diode is enabled.
