The development of a low-cost and high-precision water level indicator and controller using Arduino Uno and an ultrasonic sensor is the focus of this research study. The system aims to accurately measure the water level in a tank or reservoir and control water flow automatically. The research study involves designing and implementing the water level indicator and controller using arduino uno and an ultrasonic sensor. The system is designed to be low-cost and easy to install, making it ideal for use in households, small businesses, and rural areas. The ultrasonic sensor is used to measure the distance between the water surface and the sensor. The arduino uno microcontroller then calculates the water level using this distance measurement and controls water flow using a motor or a solenoid valve. The system's performance is evaluated based on its accuracy, reliability, and response time. Environmental factors such as temperature and humidity are also considered in the evaluation process. The research study shows that the water level indicator and controller using arduino Uno and an ultrasonic sensor is a reliable and cost-effective solution for water management. The system can help prevent water wastage, reduce water bills, and ensure a steady water supply. The research study provides valuable insights into the development of low-cost and high-precision water level indicator and controller systems and their potential applications in water management.
