## Description

The Gravity Laser PM2.5 Air Quality Sensor uses laser scattering to measure suspended particulate matter concentrations in the air. It detects particles from 0.3 to 10 µm in diameter and outputs digital concentration data via a serial interface — ideal for building air quality monitors, weather stations, and environmental sensing projects with Arduino. The sensor provides real-time PM1.0, PM2.5, and PM10 concentration readings in µg/m³, with a response time under 10 seconds. It comes with an adapter board and cable for easy connection to Arduino and other microcontrollers. Key Features Laser Scattering Detection – Accurate particulate matter measurement Three Size Ranges – Measures PM1.0 (0.3–1.0 µm), PM2.5 (1.0–2.5 µm), and PM10 (2.5–10 µm) Digital Output – Concentration and per-particle quality data via serial interface Fast Response – Under 10 seconds Low Standby Power – ≤200 µA in standby mode Long Lifespan – MTBF ≥5 years Specifications Supply Voltage – 4.95–5.05 V Max Current – 120 mA Measuring Range – 0–1000 µg/m³ Particle Size Range – 0.3–10 µm Response Time – ≤10 s Operating Temperature – –20 °C to 50 °C Operating Humidity – 0–99% RH Dimensions – 46 × 35 × 20 mm Ideal For Indoor and outdoor air quality monitoring Environmental sensing and weather stations Smart home air purifier integration HVAC monitoring and control systems Package Contents 1× PM2.5 Laser Dust Sensor 1× PM2.5 Sensor Adapter 1× Sensor Adapter Cable Resources Wiki Documentation Arduino Library (ZIP)
