Product Description:
YJJ APM10 laser Scattering Principle of laser Particulate Sensor Is Applied to Fresh Air System
Features:
Working principle
Based on the principle of laser scattering, by measuring the scattering intensity of particles in the air, combined with the Mie theory, the concentration and size distribution of particles can be calculated.
Measurement range
Particle size range: 0.3μm to 10μm
Concentration range: 0 - 1000μg/m³ (measurement accuracy of PM2.5 concentration ±15% of reading)
Technical Specifications
Supply Voltage: 4.75~5.25V DC
Operating Current: Approximately 50mA
Standby Current: Less than 3mA
Size: 49×31.5×10.8mm (Ultra-thin design)
Temperature Range: -10°C to +70°C (Operation), -30°C to +85°C (Storage)
Performance Characteristics
Resolution: 1 μm resolution
Data Refresh Rate: Up to 1 times per second
Stability: Fully metal shielded casing, strong anti-interference capability
Calibration Method: Self-calibration upon startup
Application scenario
Suitable for devices such as air purifiers, fresh air systems, air conditioners, etc., and supports digital output interfaces (such as UART/I²C).
