A rain sensor or rain switch is a switching device activated by rainfall. There are two main applications for rain sensors. There are two main applications for rain sensors. The first is a water conservation device connected to an automatic irrigation system that causes the system to shut down in the event of rainfall.
The present weather sensor (PWS) is a component of an automatic weather station that detects the presence of hydrometeors and determines their type (rain, snow, drizzle, etc.) and intensity. It works on a principle similar to a bistatic radar , noting the passage of droplets, or flakes, between a transmitter and a sensor.

Electronic components used to make a simple water detector: battery, resistor, transistor, water sensor and piezoelectric buzzer for audible alert A water detector is an electronic device that is designed to detect the presence of water for purposes such as to provide an alert in time to allow the prevention of water leakage.
A screen in general terms is a barrier. [4] The rainscreen in a wall is sometimes defined as the first layer of material on the wall, the siding itself. [2] Also, rainscreen is defined as the entire system of the siding, drainage plane and a moisture/air barrier.
