{"title":"Gravity: Laser PM2.5 Air Quality Sensor For Arduino","handle":"gravity-laser-pm2-5-air-quality-sensor-for-arduino","url":"/products/gravity-laser-pm2-5-air-quality-sensor-for-arduino","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.\n\nThe 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.\n\nKey Features\n\n\nLaser Scattering Detection – Accurate particulate matter measurement\n\nThree Size Ranges – Measures PM1.0 (0.3–1.0 µm), PM2.5 (1.0–2.5 µm), and PM10 (2.5–10 µm)\n\nDigital Output – Concentration and per-particle quality data via serial interface\n\nFast Response – Under 10 seconds\n\nLow Standby Power – ≤200 µA in standby mode\n\nLong Lifespan – MTBF ≥5 years\n\n\nSpecifications\n\n\nSupply Voltage – 4.95–5.05 V\n\nMax Current – 120 mA\n\nMeasuring Range – 0–1000 µg/m³\n\nParticle Size Range – 0.3–10 µm\n\nResponse Time – ≤10 s\n\nOperating Temperature – –20 °C to 50 °C\n\nOperating Humidity – 0–99% RH\n\nDimensions – 46 × 35 × 20 mm\n\n\nIdeal For\n\nIndoor and outdoor air quality monitoring\nEnvironmental sensing and weather stations\nSmart home air purifier integration\nHVAC monitoring and control systems\n\n\nPackage Contents\n\n1× PM2.5 Laser Dust Sensor\n1× PM2.5 Sensor Adapter\n1× Sensor Adapter Cable\n\n\nResources\n\nWiki Documentation\nArduino Library (ZIP)\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":12400,"title":"Default Title","sku":"DF-SEN0177","price":92.43,"on_sale":false,"in_stock":true,"available_quantity":3,"option1":"Default Title"}]}
