Gravity: Capacitive Non-contact Liquid Level Sensor(3mm TR, IP67)

The Gravity Capacitive Non-contact Liquid Level Sensor is a compact 5V digital detector designed for sensing conductive fluids without making physical contact. Mounting to the outside of non-metallic containers with wall thicknesses up to 3mm, it provides a clean, contamination-free monitoring solution for students, makers, and prototyping engineers.

Non-contact sensing through thin walls

This sensor detects 0 to 100°C conductive liquids through non-metallic containers with a wall thickness of up to 3mm. It outputs a digital low signal upon detection, making it ideal for test tubes, beverage machines, and small water pipes.

IP67 sealed waterproof construction

Built with a seamless shell and fully enclosed waterproof glue encapsulation, the sensor achieves an IP67 rating to block dust and moisture. The attached cable is flexible, durable, waterproof, and oil-proof to safeguard internal circuitry in harsh environments.

Direct Gravity interface connection

Featuring a standard Gravity digital interface, this module connects straight to microcontrollers such as the Arduino UNO without complex external circuitry. It runs efficiently on a 5V supply with a working current of less than 5mA.

Resilient temperature and operating range

The module operates reliably in ambient temperatures ranging from -5°C to 80°C and supports fluid temperatures up to 100°C. Its compact footprint makes it simple to integrate into tight experimental or automated liquid dispensing setups.
