Gravity: Laser PM2.5 Air Quality Sensor

The Gravity: Laser PM2.5 Air Quality Sensor is a compact detection module designed to measure airborne particulate concentrations in real time. It is an ideal addition for students, educators, and makers developing indoor air quality monitors, environmental sensing stations, and automation projects. Featuring a standard digital output, it connects readily to compatible microcontroller development boards.

Multi-range particulate monitoring

This sensor tracks PM1.0, PM2.5, and PM10 particulate levels simultaneously. It provides comprehensive air quality data across standard fine dust classifications.

Fine particle size measurement

The module uses laser scattering to detect airborne particles ranging from 0.3 to 10 μm in diameter. This allows for accurate readings across a wide range of airborne contaminants.

Fast response time

With a response time of 10 seconds or less, the sensor delivers rapid measurement updates. This speed is well suited for real-time feedback and environmental alert systems.

Standard digital output

The unit features a digital output designed for easy integration with Gravity-compatible microcontrollers. This simplifies wiring and accelerates development for prototyping projects.
