To keep from wasting water, sprinklers should be fitted with automatic rain sensors and directed only at plants, not sidewalks and driveways.

The rain sensor and automatic headlight control standard for all Sedans and Sports Wagons.

If you are getting rain, set hose-sprinkler systems on manual or attach a rain sensor to the system.

Robotic lawn mowers are increasingly sophisticated, are self-docking and some contain rain sensors if necessary, nearly eliminating human interaction.

There are two main applications for rain sensors.

Total internal reflection is the operating principle of automotive rain sensors, which control automatic windscreen/windshield wipers.

Also, install a rain sensor to shut off the device when it rains.

Vehicles are now available with driver-programmable intelligent (automatic) windscreen wipers that detect the presence and amount of rain using a rain sensor.

New on this generation were some advanced options such as rain sensor controlled windshield wipers and automatic climate control.

Another way to save water, Mr. Ratajewicz said, is to install a rain sensor that automatically prevents watering during and after a rainfall.
