Microcontroller based Pump Control system

Abstract

This project deals with how to use the Microcontroller based to control a pump system. The automatic pump controller eliminates the need for any manual switching of pumps Installed for the purpose of pumping water from a reservoir to an Overhead tank. It automatically switches on the pump when the water level in the tank falls below a Certain low level (L), provided the water level in the reservoir is above a certain level (R). Subsequently, as the water level in the tank rises to an upper level (M), the pump switches off automatically. The pump is turned on again only when the water level again falls below level L in the tank, provided the level in the reservoir is above R. This automated action continues. So we can used the automatic pump controller for several tanks. The circuit is designed to ‘overlook’ the transient oscillations of the water level which would otherwise cause the logic to change its state rapidly and unnecessarily. No use of any moving electro-mechanical parts in the water-level sensor has been made. This ensures quick response, no wear and tear, and no mechanical failures. The objective is to ideal by using the programmable Microcontroller to control the pump user so as to reduce the cost and increase efficiency by using the automatic switches in more application purposes.
