Description
The DFRobot Gravity PM2.5 Air Quality Sensor is a laser-based particle detection module designed for accurate monitoring of airborne particulate matter. It measures PM1.0, PM2.5, and PM10 concentrations using the laser scattering principle and outputs digital data via an I2C interface. The module operates at 3.3–5V and supports continuous particle counting with high consistency and fast response time. Designed for stable performance and easy integration through the Gravity interface, it is suitable for indoor air monitoring systems, environmental instruments, and smart ventilation applications. Features • Laser scattering particle detection technology • Measures PM1.0 PM2.5 PM10 concentrations • I2C digital communication interface • Gravity plug-and-play connector • 1µg/m³ concentration resolution • Fast response time under 1s • Wide 3.3–5V operating voltage • Low standby current ≤2mA • High particle counting efficiency ≥98% @ ≥0.5µm • Compact 67 × 40 × 14 mm design Tutorials • DFRobot Gravity PM2.5 Air Quality Sensor Tutorial
