Water Sensor Module for Arduino Moisture / Drop / Depth of Water Test - Red

Applications

1. Use as a level in a tank- To use it as a level detector in a deposit have to install the sensor on the inside of the tank at the level where we want to control the water level.
2. Use as rain detector- To detect whether it is raining with this sensor have to position it horizontally so that rain falls on the sensor, as raindrops fall on the sensor film of water on the surface will be formed by increasing the value of the pin S, this how we can deduce if it is raining.
