Fog Sensor (MiniOFS), Color : White

MiniOFS is designed by Dr. Sten Löfving is used to make direct measurements of visual range. The sensor is sensitive for particles in a zone about 25 cm ahead of the location of the sensor who  limit the visibility in the air. These particles are normally the microscopic water particles constituting fog, but they may also be snowflakes, raindrops or air pollutants. But the most indications of low visibility are because of fog or snow.
