The sensors can be integrated into a variety of instruments associated with a concentration of airborne particles to improve equipment, provide timely concentration, and have Exact data.
Present the laser that scatters products on airborne particles, at the same time at a specific angle collect scattered light, changing the intensity curve that scatters over time.
The microprocessor uses the algorithm based on the MIE theory to deduce the grain size contained in the air and the concentration of the particles per unit and quantity. Characteristic: - Power supply: 4.5-5.5 VDC
- Measurement range: 0.3-1.0ï¼ ›1.0-2.5ï¼› 2.5-10 µm (micrometer)
- Accuracy of count: 50%@>
