DFRobot Gravity: PM2.5 Air Quality Sensor I2C
This sensor is used to measure the concentration of particulate matter (PM) in the air. PM2.5 is a particularly harmful type of PM that can be inhaled and cause respiratory problems. The sensor uses an I2C interface to communicate with other devices.
Features:
Measures PM2.5, PM10, and PM1.0 levels
Measures humidity and temperature
I2C interface for easy integration
Low power consumption
Compact size
