Product overview

Part Number: Grove – Water Sensor

Manufacturer: Seeed Studio

Product Category: OTHER PARTS

Update Date: 2024-05-20

Detailed Information

This water sensor module is part of the Grove (Twig) system. This sensor works by having a series of exposed traces connected to ground and interlaced between the grounded traces are the sens 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.
