Grove - Water Sensor detects the presence of water using exposed PCB traces. The sensor is made up of interlaced traces of Ground and Sensor signals. The sensor traces are weakly pulled up using 1 MΩ resistor. The resistor will pull the sensor trace value high until a drop of water shorts the sensor trace to the ground trace. This circuit will work with digital I/O pins of Arduino or you can use it with the analog pins to detect the amount of water induced contact between the grounded and sensor traces.

Q: when will this product be available?? Questioned by GoutamDas, 10-May-2014

Q: Can we immerse the whole sensor into water? If not possible to immerse it, then can we solder long wire with the connector of the sensor so that we can put the wires into water (such as inside the pipe or water tank)? Questioned by ahmed.lipon, 08-Dec-2014
