This Water Sensor is designed for water detection, which can be used in sensing the water level and leakage. This sensor works by having a series of exposed copper traces which will turn on the transistor when water droplets shot the copper traces.
This sensor works with the digital I/O pins of your Arduino board. You can also use it with the analog pin for more precise measurement.
