Non-contact 5V liquid level sensor for Arduino. IP67 waterproof, detects through 3mm walls. Ideal for tanks, labs & beverage machines.
The DFROBOT Gravity Capacitive Non-contact Liquid Level Sensor is a compact, sophisticated module designed for the precise, non-invasive detection of liquid levels. Utilising capacitive sensing technology, it can accurately measure the level of conductive liquids (0–100°C) through non-metallic container walls up to 3mm thick, making it ideal for applications where direct contact with the liquid is undesirable or impossible.
Operating on a 5V supply with a low working current (<5mA), this sensor is perfectly suited for integration with popular microcontroller platforms like Arduino UNO via its convenient Gravity interface. This plug-and-play connectivity simplifies wiring and accelerates project development. It outputs a simple digital signal (low level) when liquid is detected, providing reliable and easy-to-process data for your control systems.
Built for durability in demanding environments, the sensor boasts an IP67 protection rating. Its construction features an integrated seamless shell and a fully enclosed waterproof glue encapsulation process, effectively shielding the internal electronics from dust, water, and oil ingress. The attached sensor cable is equally resilient, offering flexibility, excellent conductivity, and resistance to both water and oil.
This versatile sensor is an excellent solution for liquid level monitoring in water tanks, beverage dispensers, plumbing systems, laboratory test tubes for scientific experiments, and various DIY electronics projects. Its small form factor (43mm x 33mm x 15mm) and robust design make it a reliable component for both hobbyist and professional applications requiring dependable liquid sensing.
