This project presents the design and implementation of an automatic overhead water tank level monitoring and motor controlling system using an Arduino Uno (ATmega328P). The system aims to eliminate the need for manual water level checking and motor operation, thereby preventing overflow, dry running, and unnecessary power usage. An ultrasonic sensor (HC-SR04) is used to measure the water level in the tank without physical contact. Based on the measured level, the Arduino processes the data and automatically controls a relay module that switches the water pump ON or OFF. A 16×2 LCD with an I2C interface provides real-time display of water level percentage and motor status. The system is low-cost, reliable, and energy-efficient, making it suitable for domestic, agricultural, and industrial applications. It ensures optimal water usage while protecting the motor from damage due to dry run or overfilling. This work demonstrates a practical, scalable, and smart solution for efficient water resource management.
