Rain Sensor (Automatic Wiper Control)

The System

Rain Sensor
Rain Sensor is a highly versatile device for automatic wiping of vehicle windscreen when it is wet due to moisture, raindrops or even mud. It works by reflecting harmonious light beams within the windscreen. When raindrops fall onto the windscreen, the harmony is disturbed - creating a drop in the light beam intensity. The system then activates the wiper to operate in full automatic mode.

Features

  • Automatic wiper activation and deactivation
  • Intelligent wipers speed control
  • Auto tuning for all windscreens
  • Manual override function

Benefits

  • Safety : The 10 milliseconds response time allows immediate activation of wiper when sudden splashes of water (due to puddles / potholes) that totally "blind" the driver. Without the Rain Sensor the driver would be at risk of losing control of vehicle.
  • Comfort: The driver may be subjected to many distractions like; heavy traffic, bad weather, dangerous road conditions and fatigue. The Rain Sensor reduces the driver's distraction, making driving more comfortable and relaxing. Trailing a vehicle in wet conditions is no longer a nuisance as detection of even 0.005 milliliters of water will activate the wiper.
