DFRobot Gravity Capacitive Non-contact Liquid Level Sensor

The DFRobot Gravity Capacitive Non-contact Liquid Level Sensor is a compact 5 V liquid level module that detects conductive liquids from 0 to 100°C through non-metallic container walls up to 3 mm thick.

Overview

This sensor uses capacitive sensing technology to measure liquid levels without direct contact with the liquid, making it suitable for applications where contact is undesirable or not possible. It outputs a simple digital signal (low level) when liquid is detected, providing data that can be easily processed by control systems. Its Gravity interface supports connection to Arduino UNO and compatible microcontroller platforms, and its low working current (below 5 mA) suits low-power projects.

Key Features

• Non-contact capacitive sensing through container walls up to 3 mm thick.
• Gravity interface for connection to Arduino UNO and compatible boards.
• IP67-rated construction with an integrated seamless shell and fully enclosed waterproof glue encapsulation.
• Attached cable with resistance to both water and oil.
• Detects conductive liquids from 0 to 100°C.

Dimensions and Weight

The sensor measures 43 mm x 33 mm x 15 mm and weighs 8 g, providing a compact form for both hobbyist and professional applications.

Applications

Suitable for liquid level monitoring in water tanks, beverage dispensers, plumbing systems, laboratory test tubes used in scientific experiments, and various DIY electronics projects. Its robust design supports reliable liquid sensing in demanding environments.

Choose the DFRobot Gravity Capacitive Non-contact Liquid Level Sensor when you need dependable, non-invasive liquid level detection for Arduino-based and other electronics projects.
