Gravity: PM2.5 Air Quality Sensor Brand_Particle 92 ft) scene at aThis DFRobot Gravity Air Quality Sensor can measure particulate matter in the air, such as PM2. 5, PM1. 0 and PM10. With the easy to use Gravity interface, this air quality sensor works well with most microcontrollers and comes with sample code to help you quickly build up air quality monitoring projects. Based on the principle of laser scattering, the PM2. 5 air quality sensor employs a digital universal particle sensor that can continuously collect
