Description

The WATER LEVEL SENSOR is a compact, low-power analog water level detection module ideal for monitoring moisture and liquid presence in a wide range of applications. Designed to provide accurate and stable readings, this sensor outputs an analog voltage proportional to the level of water contacting its detection pads.
Its sensitive exposed PCB traces offer rapid response to rising water levels, making it particularly useful in systems that require quick detection, such as tank overflow prevention, pump automation, and flood alert systems. The lightweight and slim construction allows easy installation, requiring only a simple connection to an Arduino, ESP32, Raspberry Pi, or any microcontroller with an analog input.
With the ability to integrate into IoT platforms, this sensor enables real-time monitoring, remote alerts, and automated water management solutions. Its wide humidity tolerance and corrosion-resistant surface design make it suitable for both home and industrial applications.
Thanks to its affordability, ease of use, and reliability, the WATER LEVEL SENSOR is an excellent choice for hobbyists, engineers, and water management systems.
