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.
