Villages are the backbone of our nation. The farmers strive hard day and night to yield very good results in their farm. They know the entire process how to produce a farm, when to provide water to the farms etc. When it is the time to water the farms, they just stop their current works then and there and rush to the farms to start the pump sets to water the farms. This project provides an excellent solution to this process. The farmer need not go to the farm to water his field. He can sit at his present place and start the motor on to water his field. No cabling or hardware connections are required to do this. Everything will be carried in a wireless fashion and this system is entirely an automated product. This project is designed in such a way that a GSM modem is interfaced to the controller through serial port along with a motor.

According to ancient Greek scripts BIOMETRICS means study of life. Biometrics studies commonly include fingerprint, face, iris, voice, signature, and hand geometry recognition and verification. Many other modalities are in various stages of development and assessment. Among these available biometric traits, Finger Print proves to be one of the best traits providing good mismatch ratio and also reliable. To provide perfect security and to make our work easier, we are taking the help of two different technologies viz. EMBEDDED SYSTEMS and BIOMETRICS. Firstly discussing about Biometrics we are concentrating on Fingerprint scanning. For this, we are using FIM 3030N/other high voltage module as a scanner. This module has in-built ROM, DSP and RAM. In this, we can store the fingerprints of up to 100 users. This module can operate in 2 modes i.e., Master mode and User mode. We will be using Master mode to register the fingerprints which will be stored in the ROM present on the scanner with a unique id. This application will be mostly used in security buildings and constructions. The persons who want to use lift, they need to use finger print module. This finger print module allow only who are already enroll. Whenever person wants to use lift, scan his image through module. If image is valid then lift doors open automatically. Otherwise it gives beep sound and door doesnt open. The DC gear motor rotates in clock and anti clockwise directions.L293D is a driver to operate DC gear motor. The validations of image scanning, lift operation and enroll process will be displayed on 16X2 LCD. Here we use 8051 as a microcontroller with 5v DC Power supply. Serial (UART) protocol is primary concern here. The heart of this project is Bio metric module which works on serial (UART) protocol. 16X2 LCD display is connected to microcontroller through digital I/O pins.

This project is aimed to design a generalized identity system for student ID and bus pass instead of two different cards, using RFID technology. Radio Frequency Identification (RFID) Card Readers provide a low-cost solution to read passive RFID transponder tags up to 2 inches away. The RFID Card Readers can be used in a wide variety of hobbyist and commercial applications, including access control, automatic identification, robotics navigation, inventory tracking, payment systems, and car immobilization. The RFID card reader read the RFID tag in range and outputs unique identification code of the tag at baud rate of 9600. The data from RFID reader can be interfaced to be read by microcontroller or PC. The significant advantage of all types of RFID systems is the non contact, non-line-of-sight nature of the technology. Tags can be read through a variety of substances such as snow, fog, ice, paint, crusted grime, and other visually and environmentally challenging conditions, where barcodes or other optically read technologies would be useless. This project can provide security for the industries, companies, etc. This project is designed on 8051 micro controller, in this project we issue an RFID card to each individual , which is unique for each student, this RFID card holds the details of the student like the name , gender etc. in an electronic memory format, using this system we can eliminate the fake bus pass, and student ID when the card is shown to the reader the information present in the card is read by the reader and displayed in to the LCD connected to the microcontroller.

Global Positioning System (GPS) satellites broadcast signals from space that GPS receivers, use to provide three-dimensional location (latitude, longitude, and altitude) plus precise time. GPS receivers provides reliable positioning, navigation, and timing services to worldwide users on a continuous basis in all weather, day and night, anywhere on or near the Earth. This ultra-sensitive GPS receiver can acquire GPS signals from 65 channels of satellites and output position data with high accuracy in extremely challenging environments and under poor signal conditions due to its active antenna and high sensitivity. The GPS receivers -160dBm tracking sensitivity allows continuous position coverage in nearly all application environments. The output is serial data of 9600 baud rate which is standard NMEA 0183 v3.0 protocol offering industry standard data messages and a command set for easy interface to mapping software and embedded devices. This project is built around 8051 micro controller, which employs a PIR sensor to sense presence of any moving objects, which we refer here to be a human. The sensor information is fed to the controller. Inside the controller we embedded a code which checks the status of the sensor. When a signal corresponding to the human presence is detected, it takes the coordinates from the GPS modem and sends the information about the location and the live human status to a mobile phone number, through GSM modem. Our project finds its application in rescue operations at the times of natural calamities like earth quakes and tsunamis, to search for the live human beings from the carcases and debris spread irregularly, where there may not be a possibility for rescue team to creep in.
