DUST SENSOR
A dust sensor is a device designed to detect and measure the concentration of dust particles in the air. These sensors are commonly used in environmental monitoring, indoor air quality assessment, and industrial applications to ensure clean air and to monitor pollution levels. They help in assessing air quality, triggering air purifiers, and providing data for health and safety regulations.
