Product Description

Water Sensor Module for Arduino and DIY Projects

Liquid Presence Detection Sensor Module

This water sensor is a simple, low-cost device designed specifically to detect the presence of water or moisture. It works by measuring the change in conductivity between two exposed traces on its surface [citation:1][citation:2].

Simple Water Presence Detection - Detects if a sensor is dry, damp, or wet
Easy to Interface - Compatible with both digital and analog pins
The sensor operates at 5V DC with low power consumption for simple projects.
It can be used to detect the presence of water, rainfall, or liquid leakage [citation:1][citation:10].
The exposed traces should not be fully submerged for long periods, and the sensor may be damaged by continuous power in humid environments [citation:5].

= Key Features =

+Water Presence Detection - Works by detecting a short circuit between exposed traces caused by water [citation:1]

+Conductive Traces A weak 1MΩ pullup resistor keeps the signal high until water bridges the traces [citation:1][citation:4]

+Simple Interface Standard 3pin connector for easy wiring

+Versatile Use - Ideal for detecting rain, moisture, or liquid spills

= Applications =

  1. Rainfall and leak detection systems
  2. Liquid overflow monitoring
  3. Dampness indicators
  4. Simple water level triggers
Simple and Effective - A fundamental sensor for detecting liquid presence
Easy Setup 3pin connection with straightforward analog or digital readings

√ Compatible with Arduino, ESP32, and most microcontrollers

√ Can be used with analog pins to read the amount of contact

√ Also works with digital pins for simple presence detection

Troubleshooting

Inconsistent or weak readings:

  • Clean the exposed sensor traces
  • Check if the sensor is too far from the water source
  • Ensure stable 5V power supply

No signal:

  • Verify VCC and GND connections
  • Check the sensor traces are not broken
  • Ensure the sensor or its traces are not completely dry
