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);
