A simple but effective Grove water sensor. Expose the electrodes to a drop of water, and the signal drops very low. Can be used with both analog and digital ports.


Description [Hide]

It's a simple and effective concept for water detection. Use a grid of electrodes, with one half attached to a very weak 1M pull-up resistor. When a water drop bridges the electrodes, the resistance falls dramatically - so much so that this Grove module can be plugged into either an analog or digital port.

Specifications

  • Grove compatible interface
  • Low power consumption
  • 20 x 20mm (0.78 x 0.78")
  • High sensitivity
