A specialized electronic component within a Smart Home Air Quality Monitor that detects, measures, and reports concentrations of particulate matter (PM1.0, PM2.5, PM10) in indoor air, enabling real-time monitoring of airborne particle pollution levels for health and environmental assessment
Working Principle
Typically uses light scattering (laser or LED) to detect particles passing through a sensing chamber, with photodetectors measuring scattered light intensity to determine particle concentration and size distribution
Common Materials
Semiconductor laser diode, Photodetector, Optical chamber, PCB, Plastic housing
Technical Parameters
  • Measurement range for particulate matter concentration (μg/m³) Per Request
Components / BOM
  • Laser Diode
    Emits coherent light beam for particle detection
    Material: Semiconductor materials (GaAs, InGaAs)
  • Photodetector
    Detects scattered light from particles
    Material: Silicon photodiode
  • Optical Chamber
    Contains air sample and optical path for measurement
    Material: ABS plastic with anti-reflective coating
  • Fan/Blower
    Draws air sample through sensing chamber
    Material: Plastic impeller with DC motor
Engineering Reasoning
0-1000 μg/m³ with 1 μg/m³ resolution at 25°C, 101.325 kPa
>95% relative humidity causes water condensation on optical surfaces, reducing light scattering detection below 10% of nominal signal
Design Rationale: Mie scattering principle disruption due to water film formation on laser window, altering refractive index from 1.52 (fused silica) to 1.33 (water), scattering cross-section reduction of 78%
Risk Mitigation (FMEA)
Trigger Laser diode current exceeding 120 mA for >100 ms
Mode: Photodetector saturation at 5.0 V output, permanent gain reduction of 40 dB
Strategy: Current-limiting circuit with 100 mA hard limit and thermal shutdown at 85°C
Trigger Accumulation of PM2.5 particles >1 mg/cm² on inlet filter
Mode: Airflow reduction below 0.5 L/min, sampling error >25% of true concentration
Strategy: Differential pressure sensor triggering at 50 Pa drop, initiating automatic backflush cycle

Frequently Asked Questions

How does this particulate matter sensor work in electronic manufacturing environments?

The sensor uses a semiconductor laser diode to illuminate particles in an optical chamber. A photodetector measures scattered light intensity, which correlates to particle concentration. This non-contact method provides real-time PM2.5/PM10 measurements without contaminating sensitive manufacturing areas.

What maintenance is required for industrial particulate matter sensors?

Regular maintenance includes cleaning the optical chamber to prevent buildup, calibrating the laser diode and photodetector every 6-12 months, and replacing the fan/blower as needed to maintain consistent airflow. The plastic housing protects internal components while allowing easy access for service.

Can this sensor integrate with existing manufacturing monitoring systems?

Yes, the sensor's PCB includes standard communication protocols (typically I2C, UART, or analog outputs) for seamless integration with facility monitoring systems, PLCs, and data loggers. This allows continuous air quality tracking alongside other production parameters in computer and optical manufacturing.

Can I contact factories directly on CNFX?

CNFX is an open directory, not a transaction platform. Each factory profile provides direct contact information and production details to help you initiate direct inquiries with Chinese suppliers.
