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 (Assembly language 8951) 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.
