Low Cost Rain Water Sensor Module

This simple rain/water sensor detects the presence of water by presenting an ohmic resistance at its output caused by water bridging its conductive probes. The amount or level of water can be estimated and is inversely proportional to the resulting resistance.

Operating Voltage: 3-5VDC
Output: Analog (resistance at terminal S)
Detection area: 4016mm
Probe Type: FR4 PCB comb pattern.

Note: For a more robust and reliable water level probe, you might want to consider using e-Gizmo Water Level Sensor/Soil moisture kit.
