Seeed Studio Grove Laser PM2.5 Dust Sensor

The Seeed Studio Grove Laser PM2.5 Dust Sensor is a new generation of laser dust detection sensor designed for the continuous and real-time monitoring of dust in the air. Delivering a stable output alongside low noise and ultra-low power consumption, this module is perfectly suited for integration into air conditioners, intelligent air purifiers, and various air quality-related IoT projects.

Unlike traditional pumping dust detection sensors, this device innovatively utilises fan blades to drive air. The air flowing through the detection chamber acts as the test sample, enabling the sensor to perform real-time and continuous testing on dust of different particle sizes. This fan-based approach ensures consistent airflow and reliable readings without the bulk or noise associated with older pump mechanisms.

Based on advanced laser light scattering technology, the sensor provides accurate, stable, and consistent readings. It offers high sensitivity, effectively detecting dust particles of 0.3 μm or greater. Designed for seamless compatibility, it can be used directly with an Arduino board, making it an excellent choice for electronics enthusiasts and developers building smart environmental monitoring systems.
