Gravity: Laser PM2.5 Air Quality Sensor For Arduino
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.
