Design and Implementation of a Microcontroller-Based Water Level Control System with Seven Segment Display for Domestic and Laboratory Application

Abstract

The domestic and laboratory applicability of a microcontroller-based water level control system is the focus of this paper. The inability to determine the upper and lower water levels in an overhead tank as well as its inability to initiate an action, warrants a control action to stop or start the pump when the water level is low or high, this is what informed the decision of this research. The use of Electronic, Electrical Machines and other associated component in designing this system, forms the basis of the methods adopted to accomplish this task. In this design when the fluid level reaches 100 percent the system stops pumping and at 20 percent, the level sensor senses that the tank is empty and the microcontroller automatically initiates the pumping following the instructions contained in the source code. In-between these two set points; any level the water reaches, the seven-segment IC will display the output. When the water table for any particular area is so low that the pump cannot suck the water, an underground sensor detects it and after three minutes, operates an alarm for the user. The design was simulated using software (proteus 8) and implemented using hardware components. The cycle continues and aids domestic residents in pumping water without switching any pump manually. This design also can also serve as a demonstration module for laboratory experimentation
