Working Principle
This industrial dust detection sensor adopts the laser scattering principle. That is, laser is irradiated on suspended particulate matter in the air to produce scattering. At the same time, the scattered light is collected at a specific angle to obtain a curve of the scattered light intensity changing with time. Then, the microprocessor uses an algorithm based on the Mie theory to obtain the equivalent particle size of the particulate matter and the number of particulate matters with different particle sizes per unit volume.
Application
5 Tips for Industrial Dust Detection Sensor
- Ensure the laser dust sensor is powered with a stable 5V DC supply for accurate readings and long-term reliability.
- The default data output is via UART at 3.3V TTL logic levels; ensure your host controller is compatible.
- Periodically check and clean the sensor’s laser window and air pathways according to the manufacturer’s guidelines to maintain optimal performance, especially in dusty environments.
- For integration, pay attention to the pin definitions: typically, Pin1 (VCC), Pin2 (GND), Pin3 (RXD/SDA), Pin4 (TXD/SCL).
- Allow the dust detection sufficient stabilisation time (typically under 10 seconds) after power-on before using the data for critical measurements.
