Product Description

This Water Level Sensor is a simple analog sensor that works on the principle of variable resistance. As the water level increases, more of the parallel copper traces on the sensor board are submerged, leading to a change in the output voltage. This change is read by the Arduino's Analog-to-Digital Converter (ADC). The sensor is finished in a vibrant red PCB with high-conductivity traces, making it highly responsive to moisture and water depth.

Key Features

  • Plug-and-Play: Easily connects to Arduino, Raspberry Pi, and other microcontrollers.

  • Analog Output: Provides a continuous range of values representing the water depth.

  • Low Power Consumption: Can be powered directly from an Arduino 5V or 3.3V pin.

  • Compact Design: Slim profile allows it to fit into tight spaces or small tanks.

  • Versatile Application: Works for sensing rainfall, water leakage, or tank levels.

Technical Details

  • Pins: 1. + (VCC): 3V to 5V power supply. 2. - (GND): Ground connection. 3. S (Analog Out): Connects to any Analog Pin (e.g., A0) on Arduino.

  • Output Value: Typically ranges from 0 (Dry) to ~600-700 (Fully Submerged) depending on water conductivity.

Prototyping and Engineering Tips from Robogears

  • Corrosion Prevention: Because this sensor uses exposed copper traces, electrolytic corrosion occurs when powered continuously in water. To prolong sensor life, power the VCC pin through a digital pin on your Arduino. Turn the pin HIGH only when you need to take a reading, then turn it LOW immediately after.

  • Calibration: Water conductivity varies based on purity. Always calibrate your code by testing the sensor in the specific liquid you intend to monitor to define your "Empty" and "Full" thresholds.

  • Anti-Slosh Logic: In tanks where water might move (slosh), use a "Moving Average" filter in your Arduino code to smooth out the readings and avoid false triggers.

Package Includes

  • 1 x Water Level Depth Detection Sensor Module (Red)

Disclaimer

This sensor is not suitable for high-acidic or flammable liquids. The upper electronic components (above the traces) are not waterproof; ensure only the trace area is submerged to prevent short-circuiting the module.
