Grove-Compatible Analog Water Detection Sensor Module

Description

Description

• Grove compatible interface
• Low power consumption
• 2.0cm x 2.0cm twig module
• High sensitivity

The Grove Water Sensor is part of the 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.
