Seeed Grove - Water Sensor (RC0603JR)

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. It indicates whether the sensor is dry, damp or completely immersed in water by measuring conductivity. 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
