HY-SLV3E Visibility Sensor MINI Present Weather Sensor


     HY-SLV3E is a low cost visibility sensor, using so called backscatter technique it measures the amount of particles in the air that limit the visibility. Smog is composed of tiny water droplets and particles. The more particles exist in air, the stronger scattered light will be measured. HY-SLV3 can output standard visibility value reading in meters by calculating intensity of scattering light.
    HY-SLV3E visibility sensor is microprocessor controlled making possible to provide: calculated visibility in meters via digital or analog signal output.
