Construction of an automated water level controller for both overhead and underground tanks with a solar power supply

Abstract

Automatic water level controller for both overhead and underground tank with a solar supply system is designed to monitor the level of water in a tank. It displays the level of water and when it is at the lower level; a pump is activated automatically to refill the tank. When the tank is filled to its maximum capacity, the pump is automatically de-energized. The system is equipped with a solar panel to provide power, making it eco-friendly and reducing costs. - The controller uses sensors to detect the water level in the tank and automatically controls the motor to turn on or off, ensuring that the water level is maintained. - The system also features an LCD display that shows the water level in the tank and various other parameters, making it easy for users to monitor the water supply. Several circuits are put together to ensure proper working of this design, and the block diagram includes the supply unit, the micro-processor unit, the sensor unit, the display unit and the pump drives unit. The power unit is responsible for turning on the entire circuit. The sensor unit is responsible for sensing the level of water and transfer the current position of water to the microprocessor. The display unit in the circuit is use to physically show the current position of water in the tank, the properties of seven segment display are been used.
