## Description

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 Resources DFRobot Product Wiki
