PM2.5 Air particle dust sensor module

Infrared Optical Sensing: Uses an infrared light-emitting diode (IRED) paired with a phototransistor to detect light scattering caused by airborne dust particles.

PM2.5 & Cigarette Smoke Detection: Specifically optimized to detect micro-particles down to 2.5 µm, including cigarette smoke, house dust, and fine environmental aerosols.

Continuous Analog Pulse Telemetry: Delivers a proportional analog voltage output signal for linear dust density monitoring and easy ADC sampling on microcontrollers.

Low Operating Power Consumption: Draws low current during active sampling, making it well-suited for continuous indoor air monitoring and energy-conscious designs.

Compact Shielded Enclosure: Housed in a durable plastic casing with an internal metal shield frame to block electromagnetic interference (EMI) and ambient light.

Housing Material: Lightweight ABS plastic body with internal metal shielding frame and pre-attached interface wiring harness.

Technical Specifications:

Sensor Type: Optical Infrared PM2.5 Dust / Particle Sensor.

Operating Supply Voltage: 4.5V – 5.5V DC (5.0V typical).

Signal Output: Analog Voltage Pulse Output.

Target Particulate Size: ≥ 0.8 µm (Optimized for PM2.5).

Color: Black Enclosure with Silver Metallic Shielding Plate.

Usage Advice: Wire to your microcontroller's analog pin (ADC); drive the internal LED via a pulse signal and sample the output voltage during the optical pulse window.

Maintenance: Keep the optical sampling chamber clear of heavy lint or liquid condensation; clean gently using dry compressed air.

Essential Air Monitoring Component: Position as an accessible, multi-purpose optical dust sensor for smart home air purifiers, HVAC filter monitors, and automated exhaust fans.

Highlight Reliable PM2.5 Detection: Emphasize how its proven optical scattering design offers a cost-effective solution for detecting fine particulate matter (2.5µm) without complex optical setups.

Recommended Cross-Sell Add-ons: Pair with GP2Y1010AU0F Optical Dust Sensor, ACEBOTT PM2.5 Air Quality Sensor, PMS5003 Dust laser Sensor Module, and CCS811 Air Quality Sensor.
