Raindrop Sensor: The raindrop sensor module detects rainfall. It works on the principle of Ohm's Law. (V=IR). When there is no rain the resistance on the sensor will be very high because there is no conduction between the wires in the sensor.28 Oct 2019
What is the advantage of rain detector?
• Help Conserve Water The primary purpose of rain sensors is to conserve water by detecting natural rain and turning off the sprinklers. When there is enough rainfall, the irrigation and sprinkler systems will stop automatically. As a result, water wastage will be reduced.12 Sept 2018

What sensor can detect rain?
A rain sensor or rain switch is a switching device activated by rainfall. 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.
What is rain alarm?
Rain Alarm Project is a simple but very useful project that detects Rain (Rain Water) and automatically triggers an alarm or buzzer. Rain water detector will detect the rain and make an alert; rain water detector is used in the irrigation field, home automation, communication, automobiles etc.9 Aug 2017
Why do we need rain sensor?
The primary purpose of rain sensors is to conserve water by detecting natural rain and turning off the sprinklers. When there is enough rainfall, the irrigation and sprinkler systems will stop automatically. Certain types of sensors can detect water evaporating, and power the sprinklers only when watering is essential.12 Sept 2018
Is a rain sensor worth it?
Saving water and money, rain sensors make perfect sense for most irrigation systems. Economical, efficient and easy to install, rain sensors are, indisputably, a good idea. Conserving water and reducing operating costs, these devices are a beneficial addition to most any system, according to irrigation experts.
What is rainwater detector?

How do rain detectors work?
The rain sensor works on the principle of total internal reflection. An infrared light beams at a 45-degree angle on a clear area of the windshield from the sensor inside the car. When it rains, the wet glass causes the light to scatter and lesser amount of light gets reflected back to the sensor.15 Dec 2017
