Water Level Sensor Module | Liquid Level Detection Sensor for Arduino, ESP32 & Raspberry Pi

The Water Level Sensor Module is a compact liquid level detection sensor designed to measure the presence and relative level of water using a series of exposed conductive traces. It provides an analog output proportional to the detected water level, making it ideal for monitoring water tanks, reservoirs, aquariums, hydroponic systems, and smart irrigation projects.

Compatible with Arduino, ESP32, ESP8266, Raspberry Pi (with ADC), STM32, and other popular development boards, this sensor is widely used in DIY electronics, IoT, robotics, and educational STEM projects.

Note: This sensor is intended for detecting water presence and approximate water level. It is not designed for long-term continuous immersion or for precise industrial liquid level measurement.
