 Product principle overview:

  • SY210 is a laser optical refractometer that detects the number of dust particles in the air and has an embedded MCU
  • Digital dust sensor for digital detection of real-time environment dust concentration by outputting directly from the operating system and outputting data
  • Unit μg/m3. Intersecting the laser light source with the optical axis of an image sensor when dusty airflow
  • Reflected light is generated through the intersection area. The image sensor detects dust reflected laser light, according to precision
  • High-speed op amp amplification and internal modulation circuit and MCU count and algorithm, operation system particle number and weight conversion,
  • Direct output of digital signals of dust concentration, this sensor can sensitively detect particles with a diameter of 1.0μm or more,
  • Repeatedly optimized and precise data processing through the built-in microprocessor MCU has greatly improved the accuracy.
  • Directly output PM2.5 concentration signal in the current environment, unit μg/m3

 Detection and application areas:

  • Air purifier, air refresher
  • Air dust detection, indoor air dust quality detection;
  • Home appliances, air conditioners, HVAC, new fans,
  • Ventilation system, smoke alarm or other dust monitoring equipment detection components
  • As non-metering instrument detection components (Note: This product does not require high reliability, safety, precision
  • Equipment and measuring instrument components);
