Product Overview

The sensor detects "PM (particle matters) in the air" by optical method. This sensor uses LD (laser diode) as light-emitting device and PD (photo diode) as lightreceiving device. The LD inside the sensor emits light to the air in a detection area. The PD inside the sensor detects scattering light which correlated to the actual floating particles in the air. A Microcomputer (MCU) inside the sensor analyzes the wave profile from PD by optimistic algorithm, then output a converted mass-density (µg/m3) through I2C & UART interface.
  • Smaller size
  • High accuracy (±10%, from low to high concentrations)
  • High sensitivity & quick response
  • Maintain performance by unique Auto Calibration Function
  • Minimize dust accumulation by optimized air pathway structure and it makes possible to avoid "tracking" for electrical safety
  • To detect the floating particle in the air (PM2.5, PM10 & PM1, cigarette smoke, house dust, etc.)
