AEG MM-PM10-20S

Product Name: AEG MM-PM10-20S PM10 Particulate Matter Sensor Module

Product Category: Air Quality Sensor / Laser Dust Sensor

Model Series: MM-PM Series

Overview: The AEG MM-PM10-20S is a laser-based particulate matter sensor module designed to detect PM10 (particles ≤10μm) concentration in real time. It is integrated into AEG air purifiers and some dehumidifier models to enable automatic air quality mode adjustment.

Functional Features:

  • Real-time PM10 and PM2.5 concentration readout
  • Automatic fan speed adjustment based on air quality index (AQI)
  • Historical data logging via UART to main control board
  • Auto-calibration at power-on (zero-point check)

Compatible Models: AEG AX7, AX8, AX9 air purifiers; AEG DEA156, DEA180 dehumidifiers (air quality monitoring variant).

Installation Requirement:

  • Mount in clean air path — away from direct airflow from fan outlet to avoid false readings.
  • Connect UART TX/RX to main PCB with correct polarity.
  • Allow 30-second warm-up after power-on before reading values.

Usage Notes:

  • Clean sensor window monthly with dry lint-free cloth.
  • Do not expose to cigarette smoke directly — accelerates laser window fouling.
  • Sensor requires recalibration every 12 months using AEG service tool.
