Dtmf Based Irrigation Water Pump Control System

Abstract

As a result of advancement in technology it became easy for human beings to ease their work and at the same time complete the work with less human force, less time and with better results. In this project we look forward to telephonic signaling approach using Dual tone multi-frequency technique in controlling the various electrical loads such as irrigation water pumps situated in inaccessible areas. The present work is based on the principle of Dual tone multi-frequency (DTMF) signal received from any mobile phone to switch on-off the desired electrical loads such as in our farms, in factories, tube wells, irrigation water pumps etc. In our agricultural fields the tube wells are spread away from one another and thus operating them becomes very hectic as the person has to run from one place to another to operate the loads. Similar thing happens in our households also. Keeping this thing in mind a system has been designed so that it can ease the farmer as well as save time using the DTMF technology to control the loads remotely.
