DUAL GSM MODEMS BASED IRRIGATION WATER PUMP CONTROLLER FOR ILLITERATES

Aim: The main objective of this project is to develop an embedded system, which is used to control the wireless field motor using Transmitter and Receiver GSM Modems.Implementation:This project is implemented 8051 based at89s52 developed board interfaced with Transmitter and Receiver GSMs, h-bridge driver and motor.

Description:This project essentially involves two boards one is Transmitter board and Receiver board. Transmitter board consists of keypad, GSM and Micro controller The objective of this project is to design an embedded system which can control field motor remotely. This project is designed to study the basic implementation of GSM Technology In the transmitter board we will type the message through keypad to operate motor. Receiver board receives message and operated the Motor. And the wired sensor is used when the water is recvied to certain level then it sends status msg to Receiver board from the Transmitter board The system uses a compact circuitry build around flash version of at89s52 microcontroller with a non volatile memoryPrograms are developed using embedded c, compiled using ride tool. Isp is used to dump the code into microcontroller.Software: Embedded cRide to write codeIsp to burn the chip
