Safe Area Fog Detector
The visibility detector will be installed on the railing on a side of the deck. It measures atmospheric visibility (meteorological optical range) by determining the amount of light scattered by particles (smoke, dust, haze, fog, rain, & snow) in the air that passes through the sample volume.
When the air is clear, very little light is scattered, resulting in a small signal received. More particles, result in more scattering, hence higher received signal.
The detector has a visibility range of 10 m up to 20.000 m. LED transmitter projects light in a forward direction into the air between the heads and the light scattered is collected by the receiver on the opposite head. The resulting signal strength is converted to a visibility range.
