## Description

The Gravity PM2.5 Air Quality Sensor uses laser scattering to measure suspended particulate matter in three size ranges — PM1.0, PM2.5, and PM10 — and outputs concentration data via I2C. With a minimum detectable particle size of 0.3 µm and a response time under 1 second, it provides real-time, accurate air quality readings. The Gravity interface and included sample code make it straightforward to integrate with Arduino and other main controllers for indoor air quality monitoring, environmental data logging, and smart ventilation systems. Key Features Laser Scattering Measurement – Accurate particulate detection with zero false alarm rate Three Particle Ranges – 0.3–1.0 µm, 1.0–2.5 µm, and 2.5–10 µm I2C Data Output – Easy integration with microcontrollers Gravity Interface – Plug-and-play with DFRobot ecosystem Ultra-Thin Design – Only 12 mm thick, suitable for portable devices Six-Sided Shielding – Enhanced electromagnetic interference protection Real-Time & Continuous – Single response <1 s, comprehensive response ≤10 s Specifications Working Voltage – 5.0 V Max Current – 100 mA (standby ≤2 mA) PM2.5 Effective Range – 0–500 µg/m³ PM2.5 Maximum Range – ≥1000 µg/m³ Resolution – 1 µg/m³ Counting Efficiency – 50% @ 0.3 µm, 98% @ ≥0.5 µm Consistency – ±10% @ 100–500 µg/m³; ±10 µg/m³ @ 0–100 µg/m³ Data Interface Level – Low <0.8 V, High >2.7 V (max 3.3 V) Operating Temperature – −10 °C to +60 °C Operating Humidity – 0–95% RH (non-condensing) MTBF – ≥5 years Dimensions – 67 × 40 × 14 mm Ideal For Indoor air quality monitoring stations Smart ventilation and HVAC control Environmental data logging projects Portable air quality meters
