Construction of wireless matchbox for digital lantern using RF technology

The aim of this Construction of wireless matchbox for digital lantern using RF technology project is to control a high voltage electrical lamp control operation with the help of RF. The status of lamp control either ON/OFF can be observed on receiver side with the indication of LED. Users can control the lamp operation with the help of control buttons.

This Construction of wireless matchbox for digital lantern using RF technology project consists of an input from control buttons it sends the appropriate signals from RF transmitter, then the receiver receives the signals and performs the operation either to ON/OFF the lamp. Then it processes the data and takes necessary action and updates the status through LED.

User can simply ON/OFF the device with the help of remote communication.

Features:

1. Aims at energy conservation.
2. Provides user friendly interface.
3. Provides fast access to using RF.

Radio Identification Method Third Year ECE Project Report

Introduction to Radio Identification Method Third Year Project:

This method called the radio identification method is the automatic recognization method which works on saving and replying the data that is retrieved from the Databases by the device named as the RFID. This RFID is such a tag item which is joined or connected to the animal or a product or any person for the reason of identifying it by making the use of the radio waves in it. This RFID is a small tag which has presence of silicon chips and antennae in it. There are two types in the RFID tags namely the Passive Tag and the Active Tag. 

The Passive tag is the tag which has no interconnected power supply. The electric currents are then connected in the antennae’s which are present in the tags. This passive tags works by giving signals by setting it back the carrier path from the user reader. Here the present antennae are compulsory need to be circuited by the incoming signals waves and also by the transmitters too.

Active tags have it own interconnection supply of current in it. This interconnection current is then made in use of getting the outgoing wave signals. The defense system of the united has properly used this system to low down the price and change the production of arm weapons too. 

The latest on working applications of the radio identification method are firstly the passports here this device is to give the passports to the people applying for it. Second is the Transport payments system here payments of the online travelling tickets are made by the means of Credit Cards. Third is the product tracking in which this device is used to track the barcode number of the products which are kept on sale. Automotive and animal identifiers are couple of other applications.

Security System Using RFID ECE Project Report

Introduction to Security System Using RFID ECE Project:

The main objective of the project is to design a system that have a small coverage area which can be used for authentication or identification purposes. By using this security system we can provide entry by a access authorization process. This system is being developed by using RFID technology.

This system consists of finger print impression, camera and for looking after the authentication process. The RFID consists of RFID reader which comprises of the components working and RFID tag which maintains the transmission and reception process. In this paper we will look into the working of multi level security system. 

Brief into design and working :

This system mainly uses RFID technology. RFID is a wireless identification method. This RFID consists of RFID Tags for receiving and responding to radiofrequency queries from an RFID transceiver and an RFID reader for decoding the data sent from RFID tags.PIC micro controller which is used controls all the devices and makes them to function in time.

A finger print scanner IC is used for checking the authorization process through finger prints. ZigBee is a wireless mesh network standard.GSM technology for sending and receiving a message. When the user places the thumb impression on the scanner then the camera automatically takes the picture of the user for future verification.

This information is stored in the database along with time and date when the system was accessed and by GSM technology it makes sure that concerned authority is notified about the access.

Wireless Data Transfer Using RF Communication Project Report

Introduction to wireless data transfer:

To meet the present day technology needs, data transfers at higher speeds are to be achieved which is possible by RF communication. Wireless Data Transfer Using RF Communication Project Report elaborates the working model of RF communication techniques for data transfer. In this we find transmitter section and encoder and decoder are used for the processing of original data.

AT89C52 microcontroller is used for monitoring of the components. The programming part is designed using keil software. The transfer from the  pc to controller is done using max 232 cable.

Working process:

The data is transmitted serially from pc to the controller is done using max232 cables. The encoder, encodes the data and is transmitted by using a RF transmitted from  the transmitter circuit. The transmitted data is caught hold at the receiver circuit and is receiver circuit and is decoded by using the decoder and the decode data Can be seen in the LCD.

The circuit works on the +5v RPS. We will use TX433 and RX433, for transmission and reception of the RF signals. The software part is programmed in keil software depending upon the program the microcontroller works.

The AT89C52 micro controller has reusable flash memories which are an added advantage. The operating frequency of transmitter and receiver of RF module is about 433mhz.

 

Applications and Future-scope:

The technology has growing applications for transfer of data in banks and industries and companies. The use of RF transmission the data transfer rates are low and in the ongoing process we can achieve higher data rates by employing data compression techniques.

Vehicle Information Communication Safety Combined With Mobile RFID System Project

The main aim of this Vehicle Information Communication Safety Combined with Mobile RFID System project is to get vehicle information using Radio frequency identification tag. This ECE project mainly use the equipments of microcontroller of type LPC2148, it is a 64-pin device, RF ID reader is used to drive the vehicle, when the tag is shown to the vehicles microcontroller then access the tag and the information regarding which person is using the vehicle is directly send to the owner by using the GSM technology. In this GSM technology GSM modem is used this modem contains the SIM and the RF ID tag contains the memory, tag consists battery because tag has to send the microwaves to the microcontroller to access. So we need a battery in the tag, there are several types of the batteries, one is chargeable and other is rechargeable batteries and also here using the regulator, filters, rectifier.

The software used in this project are KEIL IDE, embedded C Programming Language, the tag internally it has some memory where one identification is present then that information is sent to the owner by using GSM modem. This project mainly used when the owners having more vehicles so to access the data regarding vehicles which rout the vehicle is going and drivers information, and in this project we can use the accident switches in the front and back side. These switches are connected to the microcontroller. Whenever accident occurs the switches are pressed and the GSM modem send the information to the owner but this project not give the information regarding the vehicle position.
