CONCLUSION

The research study will produce a new system that categorized as an upgraded system. Previously, basic locker are using a key lock as a security to their locker to prevent locker from been hack by the theft. There are advantages when using a new system which to help the user when they going outside leave the room.      

           

 The Locker Security Monitoring System is a sophisticated system to build but it is very worthwhile when the project complete. The main factor and reason why this project are develop because in collage hostel always have a cases student are loss their belonging item and gadget when the leave their room or locker. If the theft tries to open by inserting incorrect password or try to force to open the locker, the magnetic sensor automatically, detect and send the signal to PIC controller. When the PIC received the signal its will send to warden office computer through the wireless signal. From here warden will know which room or locker had been hack by theft.

 The main target user is actually for the collage hostel student. This project will help either warden or student to reduce the criminal cases in the collage hostel. Other than that its will make student fell more safety to left their personal belonging in the locker.

COMPONENT USED

PIC 16F877A

This project is outfitted with a microcontroller, Peripheral Interface Controller 16F877A (PIC16F877A). This powerful (200 nanosecond instruction execution) yet easy-to-program (only 35 single word instructions) CMOS FLASH-based 8-bit microcontroller packs Microchip's powerful PIC architecture into an 28 pin package and is upwards compatible with the PIC16C5X, PIC12CXXX and PIC16C7X devices.

 The PIC16F877A features 128 bytes of EEPROM data memory, self programming, an ICD, 2 Comparators, 5 channels of 10-bit Analog-to-Digital (A/D) converter, the synchronous serial port can be configured as either 3-wire Serial Peripheral Interface (SPI) or the 2-wire Inter-Integrated Circuit (IC) bus and a Universal Asynchronous Receiver Transmitter (USART).

SKXBEE WIRELESS

SKXBee has been designed for 5V TTL logic interface, no extra voltage divider is necessary. With minimum interface, it is ready to connect to microcontroller for embedded XBee development. Furthermore, on board

USB to UART converter offer easy yet reliable communication to PC for functionality test and as XBee dongle. SKXBee can support both XBee and XBee PRO because they are interchangeable and pin-to-pin compatible with each other.

BLOCK DIAGRAM

EXPLANATION PROCESS OF PROJECT

Figure 1 above shows a block diagram of Locker Security Monitoring System working process. The system consists of several part, starting from inserting the password, part when the locker will open and computer received the signal if their locker been hacked.

At the inserting password part, user a insert the password by using the keypad 4 x 3 size. The PIC 16F877A will trigger the password either correct or false and give the user 5 time chance. The LCD will display the number of password every time user inserting. If the passwords are correct, the door will unlock, and locker are able to open. If the password are incorrect until 6 time, the PIC 16F877A automatically send the signal to the computer true SKXBee wireless.

At the transmitter part, when PIC 16F877A trigger the password that inserting are incorrect, PIC microcontroller will interface and send a signal to transmitter. The, tha data will encoded and transmit to the receiver by using SKXBee Wireless.At the receiver, the data that receive from the SKXBee Wireless transmitter will be decoded before sent it to the personal computer. At the personal computer, the data will be monitor and analyze by using Microsoft Visual Basic 2008 Express Edition programmed. At here, the warden are able to know which locker have been hacked.
