The DFRobot Gravity PM2.5 Air Quality Sensor employs a laser scattering detection principle. A laser diode irradiates airborne particles, and a photodetector collects the scattered light at a specific angle. An onboard microprocessor uses the Mie scattering theory algorithm to calculate Particle size distribution and output real-time mass concentration data for PM1.0, PM2.5, and PM10 via a digital I2C or UART interface.
Designed for seamless integration, the module features the standard DFRobot Gravity 4-pin connector, simplifying wiring with popular development boards. Its six-sided shielding provides strong resistance to external optical and electrical interference, ensuring stable readings in varied environments from indoor air quality monitoring to portable environmental sensing projects.
