Water Level Sensor Module

The Water Level Sensor Module is designed to sense water contact and measure varying levels of liquid using a series of parallel copper tracks that act as a variable resistor network. When water rises on the sensor plate, electrical conductivity increases, reducing resistance and generating a proportional analog voltage output.
This signal can be read by microcontrollers such as Arduino, ESP32, ESP8266, STM, and Raspberry Pi for real-time water level monitoring and automation.
The module operates at low voltage and includes an onboard power indicator for easy diagnostics. Its simple interface and high sensitivity make it suitable for water tanks, environmental monitoring systems, leakage detection, irrigation management, and liquid-based experiments.
