Description
Specifications

The Water Sensor module is part of the Grove system. It indicates whether the sensor is dry, damp or completely immersed in water by measuring conductivity. Grove - Water Sensor can detect the presence of water using exposed PCB traces. The sensor traces have a weak pull-up resistor of 1 MΩ. The resistor will pull the sensor trace value high until a drop of water shorts the sensor trace to the grounded trace. Believe it or not, this circuit will work with the digital I/O pins of your Arduino or you can use it with the analog pins to detect the amount of water induced contact between the grounded and sensor traces.

Features

Precise measurement: The sensor measures the number of water droplets/water flow through a series of exposed parallel wire tracks to determine the water level.
Digital output: It's easier to read the water/no water state by judging high and low levels.
Grove compatible interface: The product ensures "Plug and Play" and could be versatile for various applications of Grove.

Applications

Rainfall detecting
Liquid leakage
Tank overflow detector
