This PM2.5 dust sensor uses an optical system to effectively detect very fine particles, including cigarette smoke, making it a reliable component for air purifiers and air quality monitoring instruments. The sensor integrates an IR LED and a phototransistor, which work together by having their beams crossed to detect the reflected light from dust particles in the air. It features ultra-low power consumption and can be operated with a supply voltage of up to 7VDC, ensuring energy efficiency and versatility. This sensor is suitable for air purifiers and other devices designed to measure air quality, and it undergoes strict quality control to guarantee high safety and reliable performance.
