text: Visibility sensors detect atmospheric transparency and output a sensor equivalent visibility (SEV) range that represents the maximum distance that the human eye can see under given atmospheric conditions. They offer a standardized method for assessing visibility range when it is impaired by fog, cloud cover, snow, smoke, or other precipitation. Meteorologists use visibility sensors to remotely monitor the visibility range. They may be deployed in remote weather stations while the most common application for visibility sensors is for aviation when assessing visibility at runways.
