Abstract	This paper presents the design and implementation of an automated water tank controller using Hall effect sensors and a floating magnet system. Traditional water level monitoring systems suffer from reliability issues due to corrosion, sediment accumulation, and mechanical wear. To address these problems, the proposed system employs non-contact Hall effect sensors to detect water levels, which in turn automatically control a water pump. The circuit uses a comparator and relay-based mechanism to switch the pump on or off based on real-time sensor input. This approach ensures precise measurement, high reliability, and minimal maintenance. The system was tested under different water levels, and results demonstrated consistent performance, validating its suitability for both residential and industrial applications.
