Notice boards play a vital role mostly in educational institutions. The events, occasions or any news, which has to be passed to the students, will be written on the notice boards present in every floor in the colleges or schools. The present system is like, a person will be told the news and he has to update this news on all the notice boards present in the college or school. This will be seen mostly during the examination seasons. The time table or the schedule of the exams has to be given to the students. This will be done by writing the details on the notice boards. But this process consumes a lot time to update the news on all the notice boards and there may be chances that the person responsible may commit some mistakes or he may be absent sometimes. So, this may create disturbances and the entire schedule may be disturbed. To avoid all these, Wireless Notice Board have been designed which completely eliminates the manual work. ZIGBEE is a specification for a suite of high level communication protocols using small, low-power digital radios based on the IEEE 802.15.4-2003 standard for Low-Rate Wireless Personal Area Networks (LR-WPANs). ZIGBEE is targeted at radio-frequency (RF) applications that require a low data rate, long battery life, and secure networking. ZIGBEE protocols are intended for use in embedded applications requiring low data rates and low power consumption. ZIGBEEs current focus is to define a general-purpose, inexpensive, self-organizing mesh network that can be used for industrial control, embedded sensing, medical data collection, smoke and intruder warning, building automation, home automation, etc. The resulting network will use very small amounts of power.

At the receiving end, the controller will be interfaced to the LCD and an other XBEE transceiver. The transceiver receives the data coming from the transmitter and the same data will be fed to the microcontroller . The controller sends this data to the display unit and thus the message given by the user at the transmitter end will be displayed on 16X2 LCD display. This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation.

But there may be chances that the person may forget to operate , and also it is not an easy task for a person to operate these loads manually as these loads run with high voltages. This project gives the best solution for these problems. Here in this project, the wireless communication between the remote areas will be achieved by using the RF modules called RF transmitter and RF receiver. The project is designed in such a way that we will interface four switches to an 8 bit microcontroller 8051 to control the various loads which will be connected on the receiver side. And the RF transmitter is also interfaced to the controller through an RF encoder to encode the data received by the controller. Hence the encoded data will be transmitted by the transmitter over the medium and will be received by the RF receiver which will be interfaced to the controller through an RF decoder, on the receiver side. The RF decoder is used to decode the received data into a 4 bit digital data which will be fed to the controller. So now the controller will perform the predefined tasks by monitoring the received decoded data. The loads which have to be operated will be interfaced to the controller through relays. And these loads will be turn ON/OFF based on the ON/OFF conditions off the switches on the transmitter side. An LCD will also be provided to display the status of the loads. This project is not only limited to industrial applications but can also be extended to domestic purposes as home appliances controlling using RF. The home appliances can be switched on/off using this RF concept without actually going near the switch boards or regulators. This project uses regulated 5V, 500mA power supply. Unregulated 12V DC is used for relay. 7805 three terminal voltage regulator is used for voltage regulation. Full wave bridge rectifier is used to rectify the ac output of secondary of 230/12V step down transformer. scribe the project here   Micro Controller : AT89S52 Crystal : 11.0592 MHz RF Encoder: HT12E RF Decoder: HT12D Relay Loads Software Requirements Keil Proteus Uc Flash Embedded C Prog Isp

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. In this project, the RFID module reader typically contains a module (transmitter and receiver), a control unit and a coupling element (antenna). This module is interfaced with the micro controller and when the card is brought near to the RFID module, it reads the data in the card and displays on the LCD. If the data in the card is matched with the data stored in the program memory, then it compares and displays authorized message. If the data is not matched it displays unauthorized. For authorized message, the door will be opened and closes automatically after a small delay. If it is an unauthorized person it alerts the persons through a buzzer. The RFID module alerts the buzzer whenever it reads the data from the RFID card. The door will drive by DC gear motor by l293d driver. 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. In this project 7805 is a regulator and it avoids noise spikes in power supply.
