GP2Y1010AU0F sensor utilizes light scattering technology to measure PM2.5 levels in the air. Operates on a working voltage of DC5.0V. Provides an analog voltage output signal ranging from 0-5V. Capable of detecting various heavy metal elements and self-generated pollution, including volcanic ash and fine particulate matter from natural events. Ideal for applications in PM2.5 air detection systems, air quality monitoring, and pollution alert systems. GP2Y1010AU0F is a sensor that uses light scattering to measure PM2.5 in the air. Inside the sensor, there is a light source that illuminates the dust in the air. When there is dust in the air, the light will be reflected. At the other end of the sensor, there will be a light intensity receiver. The sensor determines the concentration of dust in the air based on the value collected by the receiver. The light scattered by these dust enters the light receiving element as voltage output. It is commonly used in air particle pollutant detection and alarming, air quality detection, and other designs.
