What Is A Particle, Dust monitor?

Particle, Dust Sensors are sensors used to detect the concentration of fine particles and dust in the air. They can detect particles in different size ranges, such as PM10 and PM2.5, which can have health and environmental impacts. Particle, Dust Sensors are widely used in applications such as air quality monitoring, indoor air purifiers, industrial environmental monitoring, and personal health tracking, providing real-time air quality data and monitoring.

Working principle of particle counter

Particle counters utilize the light scattering method for detection. They draw in ambient air through an inlet nozzle and direct laser light into the measurement area. When the emitted light interacts with particles, it scatters. A photodiode within the particle counter detects this scattered light and converts it into an electrical signal. The particle size is determined by the strength of the voltage signal, while the total number of particles is calculated based on the number of waveforms detected.
