Water Level Sensor – Analog Output 3–5V

The Water Level Sensor is an analog detection module designed for measuring liquid levels in tanks and containers. It operates by using parallel exposed conductive traces to detect water presence and convert it into a variable analog signal. Operating at 3–5V DC with low current consumption, it provides stable and reliable readings compatible with Arduino and other microcontrollers. Its compact PCB layout ensures easy integration into water level monitoring, overflow detection, and automated irrigation systems.
