OTP AND BIOMETRIC TECHNOLOGY BASED LOCKER SYSTEMS

OTP AND BIO-METRIC TECHNOLOGY BASED LOCKER SYSTEM:


INTRODUCTION OF PROJECT:

       User home security is the prime concern for every user as it provides opportunities for them to work freely without worrying  about the home security. This OPT and Bio-metric Technology Based Locker System project provides a security system for the user’s house. For this, it takes the help of GSM Technology, each use will have a unique ID code for the user’s door. The security system will generate a unique encrypted code for user’s access and will SMS it to user with the help of GSM module, user needs to enter this code in order to open the door, otherwise the system denies the access and lock the door.

Description:

Mobile Phone  
 In this project we have used one cell phone for user to send a unique code to his mobile. User’s  cell phone will use GSM Network for communication
Microcontroller Micro-controller 8051 is the most important segment of the project. The controller is responsible for detection and polling of the peripherals status. It is responsible for prioritizing all the devices attached to it.  We have used the PHILLIPS  89V51 micro-controller, low-power, high-performance CMOS 4-bit micro-controller with 8K bytes of in-system programmable Flash memory. 
GSM ModemGSM module helps to establish communication between a computer and a GSM-GPRS system. Global System for Mobile communication is an architecture used for mobile communication in most of the countries. Global Packet Radio Service (GPRS) is an extension of GSM that enables higher data transmission rate. 
LCD
We have used 16*2 LCD in order to display the user information.

Advantages

  1. High level of security is obtained by the use of GSM Technology
  2. Security is ensured even if the unauthorized user tries to open the door with the valid user id, as the encrypted code will only be sent to valid user cell phone
  3. Low cost, easy to use
  4. System can be easily modify for new users

Applications

  1. Home security system
  2. Personal Door Security System
  3. Jewellary Stores

Wireless Automatic Meter Reading System for Power Measurement, Load Control and Billing

Wireless Automatic Meter Reading System for Power Measurement, Load Control and Billing:   Introduction Due to use of  improper power management systems, the power requirement is increasing in the development of country’s economy. Over the past years, metering devices have improved a lot, and are expected to become even more advanced, offering more and more services. Meters in the past were electro-mechanical devices with poor accuracy and lack of ability. Recent developments in this direction seem to provide opportunities in implementing energy efficient metering  technologies that are more precise and accurate, error free, etc. The implementation of Wireless Automatic Meter Reading System(WAMRS) provides with many vital features as compared with the analogue utility meter reading with man power. Working of WAMRS: WAMRS provides a two way communication between the electricity company and the load by sending in a lot of power parameters and control s...
