Laser dust sensor: the "smart eye" that accurately senses air quality

作者:ShanXi TengXing Sensor TechnologyCo.,Ltd2025-05-12 09:32:10

1. Why do we need laser dust sensors?

The invisible threat of dust pollution

粉尘对电气设备的危害及其防治 - 知乎

Health hazards: PM2.5/PM10 can penetrate the human respiratory barrier and induce asthma and cardiovascular diseases;

- Industrial risks: Excessive dust concentration in the workshop may cause explosions (such as flour mills and lithium battery workshops);

Environmental protection needs: Countries have issued strict standards (such as China's "Air Pollution Prevention and Control Law" and EU EN 15267 certification) requiring real-time monitoring of dust emissions.

The core value of laser technology

Compared with traditional infrared dust sensors, laser technology has become the preferred solution for industrial-grade monitoring and high-end consumer electronics with its higher accuracy, smaller particle size detection capabilities (as low as 0.3μm) and long-term stability.

2.Analysis of the core technology of laser dust sensor(Take our product TZJ06 as an example)

    TZJ06 is a universal, miniaturized laser dust sensor module. Using the Mie scattering principle, it can detect dust particles in the air. Through professional algorithms and calibration detection process processing, it has good consistency and stability. The sensor has the ability to output serial port and PWM output at the same time, which is convenient to use. Small size, easy to integrate and apply.
