Core Technical Specifications
  • Operating Voltage: 4.5V to 5.5V DC (Typically 5V)
  • Current Consumption: Max 20mA (Peak current when pulsed)
  • Output Format: Analog voltage output (0 to over 3.5V)
  • Sensitivity: 0.5V per 0.1mg/m³ of dust concentration
  • Detection Range: Up to 600 μg/m³
  • Dimensions: 46.0 mm × 30.0 mm × 17.6 mm
  • Minimum Particle Detection Size: 0.8 microns
Required Circuit Interface Components
To successfully interface the sensor with a microcontroller (like an Arduino), you cannot simply connect power and read data. The internal infrared LED must be pulsed cleanly. Most retail packages include these two crucial components:
  • 150 Ω Resistor: Used to limit current to the infrared LED.
  • 220 μF Capacitor: Acts as a decoupling capacitor to stabilize power during rapid current spikes when the LED pulses.
Pin Configuration (6-Pin Connector)
  1. V-LED: Connects to 5V through the 150 Ω resistor.
  2. LED-GND: Connects directly to the system Ground.
  3. LED: Connects to a digital output pin on the microcontroller to toggle the infrared emitter.
  4. S-GND: Device circuit Ground.
  5. Vo: Analog output voltage pin connected to an Analog-to-Digital Converter (ADC) input on your microcontroller.
  6. Vcc: Main 5V power supply input.
Primary Applications
  • Smart Air Purifiers: Triggers fans when smoke or heavy house dust is introduced.
  • HVAC Systems: Air conditioners or indoor ventilation systems to monitor general air filtration quality.
  • DIY IoT Electronics: Cost-friendly introductory air pollution or fire/smoke alarm monitors.
