Description

This water level sensor operates on the principle of conductive trace sensing. A series of parallel exposed traces on the PCB act as a variable resistor; as water bridges these traces, the electrical resistance between them changes. This change in resistance is converted into a variable analog voltage output by the onboard circuitry, which can be read by an Arduino’s ADC (Analog-to-Digital Converter) pin.

The module is designed for low-voltage operation, compatible with common 3.3V and 5V logic systems. Its compact form factor and simple three-wire interface (VCC, GND, Signal) make it suitable for integration into educational projects, simple tank level monitors, and leak detection systems within its specified operating temperature range.

Key Features

  • Analog output provides continuous resolution for water level measurement.
  • Low-voltage, low-current design ideal for battery-powered or microcontroller-based projects.
  • Simple three-pin interface (Power, Ground, Analog Signal) for easy connection.
  • Compact and lightweight PCB construction for versatile mounting.
  • Exposed parallel wire sensing element for direct contact measurement.
  • Optimized performance-to-cost ratio for educational and prototyping applications.

Applications

  • Simple water tank level monitoring in small-scale hydroponics or aquariums.
  • Basement or appliance leak detection and alert systems.
  • Educational projects demonstrating analog sensing principles with Arduino.
  • Rainwater collection barrel level indicators.
  • Basic liquid presence detection in DIY electronics projects.

Frequently Asked Questions

What is the output signal type of this water level sensor?

This module provides an analog voltage output. The signal pin outputs a variable voltage between 0V and the supply voltage (VCC), proportional to the amount of water contact on the exposed parallel traces. This analog value can be read directly by an Arduino's analog input pin (e.g., A0) using the analogRead() function.

What is the operating voltage range, and can I use it with 3.3V systems like ESP32?

The module operates from 3V to 5V DC, making it directly compatible with both 5V systems like standard Arduino Uno and 3.3V systems like ESP32 or Raspberry Pi. Ensure your microcontroller's analog reference voltage matches the sensor's supply voltage for accurate ADC readings.

How does the sensor detect water level, and what is the sensing area?

It uses a series of exposed parallel conductive traces on the PCB. As water bridges these traces, it changes the resistance between them. The onboard circuit converts this resistance change into an analog voltage. The active sensing area is a 40mm long by 16mm wide section at the end of the module. The sensor must be positioned vertically for level measurement, with more traces submerged as the water rises.

Can this sensor be used with liquids other than pure water?

It is primarily calibrated for pure or tap water. Other conductive liquids may work but will affect the output reading due to different electrical conductivity. Non-conductive liquids (like oil) will not be detected. For consistent results, calibration with the specific liquid in your application is recommended.
