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 (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
