Everyone is well aware of the wastage of water through tanks, which has always been a concern. In many cities and villages, water wastage has increased as people have not maintained their tanks properly. This paper is designed to monitor and control water levels in tanks, reservoirs, or other storage containers. The proposed system utilizes a combination of sensors, microcontrollers, and actuation mechanisms to provide real-time monitoring and control of water levels. This automated approach offers numerous benefits, including improved water conservation, reduced energy consumption, and enhanced convenience. For smaller tanks, solutions such as ball valves are applicable, which automatically stop the water flow once the tank is full. This is a simple and basic idea for smaller tanks. However, in many large tanks located in buildings, hotels, schools, etc., which require a significant amount of water storage, there is a need to prevent overflow. An electronic solution can be implemented to save water. When the tank is nearing full capacity, it will raise an alarm and stop the water pump. Conversely, it can also help fill the tank when it's empty using an electronic device. The Arduino Uno-based automatic water level indicator and controller is a practical and efficient solution for monitoring and controlling water levels in various applications. This system utilizes ultrasonic sensors to measure water levels by emitting sound waves and calculating the distance based on the echoes they receive after bouncing off obstacles in the water. The Arduino Uno-based automatic water level indicator and controller utilizing ultrasonic sensors is a practical and versatile solution for managing water levels efficiently. It offers accurate measurements, automation, cost-effectiveness, and adaptability for various applications, making it a valuable tool for water level monitoring and control.
