Construction of Digital Water Level Indicator and Automatic Pump Controlling System

Abstract

In modern technology is largely depends on automation and control system. Automation and control system refers the use of various control systems for operating equipment such as machinery, processes in factories, boilers and heat treating ovens, switching on telephone networks, steering and stabilization of ships, aircraft, automobile and other applications with minimal or reduced human intervention. The greatest advantage of automation and control system is that it saves labor. A water level indicator system is a device that indicates the level of water in a tank or reservoir. It is widely used in industrial applications such as boilers in nuclear power plants and residential applications. The project is to design water level indicator with automatic water pump controlling system. water level sensor has been made for apprehended water level properly. Microcontroller is plighted to restrain the overall system accurately that reduces the control complexity. It takes input through the sensor unit that senses the water level. After taking input , output intends the  pump’s action (on/off) with respect to current water status of the tank. A display unit indicates the status of pump and water level. The device also monitor the state of level of water whether it is stable, increasing or decreasing with what velocity. It also stores the total time of pump being kept ON. It also keep monitoring whether the pumping is working well or not. While Keeping the motor ON it detects whether the motor pump is working well or not every minutes. If the level is increasing or decreasing in each minutes then the indicator shows the motor pump is working well else after three minutes if the level remains stable then it shows there is a problem in motor. Thus it also monitor the working performance of the pump.
