Quick Overview

Designed for low visibility detection, the Mini Optical Fog Sensor, is a compact and easy to install solution with its compact dimensions. Ideal for early detection for traffic safety, the MiniOFS can be integrated into many existing systems via its simple 0-5V or RS232 outputs. Visibility ranges from 20 meter to 4 kilometres, the unit is capable of detecting fog as well as snow, raindrops and air pollutants.

The MiniOFS is designed for visbility monitoring, specfically fog detection, by looking at miniture particles about 25 cm infront of the sensor.  These particles, typically microscopic water which constitues fog, however they may also be snow, rain or air polutants.  The sum of which can inhibit visibility which can cause dangerous driving conditions.

The internal microprocessor calculates the visibility and outputs the data in a simple RS232 format or a linear voltage output allowing easy connection to multiple monitoring systems, data loggers and data acquisition equipment.
