Development of an Automated Liquid Level Control System Using Arduino Microcontroller

Abstract - This research presents the development of an automated liquid level monitoring and control system using an Arduino microcontroller. The system utilizes ultrasonic sensors to accurately detect the liquid level within a storage tank, providing real-time data for level indication and automated control. The Arduino serves as the central controller, processing sensor input and managing the operation of pumps and solenoid valves based on pre-defined threshold levels. This ensures efficient and automatic filling, monitoring, and distribution of liquids. Designed for both residential and industrial applications, the system supports the handling of various liquids, including water, acids, and other chemical solutions. It offers a reliable and hands-free solution for managing liquid storage tanks, reducing human intervention and preventing overflow or dry-run scenarios. The system is scalable, cost-effective, and environmentally friendly, making it suitable for a wide range of fluid management needs.
