Water Level Depth Detection Sensor Module

Water Level Depth Detection Sensor Module 

A water level depth detection sensor module is an electronic device used to measure the level or depth of water in a tank, reservoir, or container and convert it into an electrical signal that a microcontroller or control system can interpret. These modules vary in sensing technology — such as resistive, capacitive, ultrasonic, or optical — to detect the presence and sometimes the approximate depth of liquid. They are widely used in automation systems, pump controllers, and smart water management applications because they provide real-time level information without complex hardware or continuous manual checking.
