A non-contact capacitive liquid level sensor designed for small-diameter pipes (outer diameter ≤10 mm). Detects the presence or absence of liquid through the pipe wall without any physical contact with the liquid — making it safe for corrosive substances like strong acids and alkalis.
Features adjustable sensitivity, a status indicator LED, and a 4-pin sensor adapter for direct digital signal connection to Arduino or other microcontrollers. Provides real-time level feedback with ±1.5 mm accuracy.
Key Features
- Non-Contact Detection – Senses liquid through the pipe wall using capacitive technology
- Small Pipe Compatible – Designed for pipes with outer diameter ≤10 mm
- Adjustable Sensitivity – Tune detection threshold for different pipe materials and liquids
- Status Indicator LED – Visual feedback of liquid detection state
- Digital Output – 4-pin adapter for direct connection to microcontrollers
- IP65 Waterproof – Suitable for wet environments
Specifications
- Power Supply – 5–24V
- Output – Digital switch (high/low)
- Response Time – 500 ms
- Operating Temperature – -5 to 105°C
- Suitable Pipe Diameter – ≤10 mm (outer diameter)
- Liquid Level Accuracy – ±1.5 mm
- Material – ABS
- Waterproof Rating – IP65
Ideal For
- Water dispensers and small pipe monitoring
- Medical and laboratory perfusion tube detection
- Corrosive liquid level monitoring (acids, alkalis)
- Arduino and microcontroller-based liquid sensing projects

Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
