Simple Water Detection Sensor with Digital Output is backordered and will ship as soon as it is back in stock.


DESCRIPTION

Keep wet things wet and dry things dry by detecting when the dry things get wet by accident! This palm-sized cherry-red water sensor is simple and easy to implement in your wet-dry-sensing project.

Usage is very simple: connect the minus (-) pin to ground, connect the plus (+) pin to 3 to 5V DC and then the output signal pin (S) goes to your microcontroller

The sensor has a very lightly biased transistor that is connected to two long sets of interlocking traces. When a little bit of water/condensation lands on the PCB and touches two of the traces, the transistor will turn on, setting the output pin high. The output voltage does vary a bit with how much water is detected, but honestly, we recommend just using it as an "on or off" type sensor.

FEATURES
  • Dimensions (including header) 64.7 x 20 x 7.7mm
  • Weight: 3.7g
