INTRODUCTION“KEYPAD INTERFACED ZIGBEE BASED SECURITY SYSTEM”
This project is being design for security purpose
It has two stages of security
1) Keypad
2) ZigBee
It is based on Embedded System
It is combination of hardware and software
HARDWARE REQUIRED
• Microcontroller Atmega 16• Keypad• ZigBee• LCD 16x2• Motor Driver IC L293D• Motor• Voltage Regulator 7805

PIN DIAGRAM
ZIGBEE• ZigBee is a IEEE 802.15.4-based specifications for a
suite of high-level communication protocols used to create personal area networks with small, low-power digital radios.
• It is simpler and less expensive than other wireless personal area networks (WPANs), such as Bluetooth or Wi-Fi.
• Uses: Electric Meters, Thermostats, Security Systems, Light Switches, Traffic Management, Projects.
ZIGBEE Contd…
• It has a non standard pin size.
• UART interface. Uses tx-rx.• To Program ZigBee use a
FTDI UART to USB convertor.
• ZigBee uses 3.3 volts.• Its range is 10-100m.
Zigbee
OVERVIEW OF LCD DISPLAY• This can be easily connected with
microcontroller and microprocessor• 16x2 Is most popular LCD display• It has 2 rows & 16 columns• LCD has two registers, namely,
Command and Data• The command register stores the
command instructions given to the LCD
• The data register stores the data to be displayed on the LCD
LCD Display 16x2
MOTOR DRIVER IC L293D
Motor Driver IC L293D
• Motor driver IC L293D is used to provide interface between MCU & Motor
• It has two H-bridge driver• Motor driver IC does not
amplify the current ; it only acts as a switch.
• Output current per channel = 600mA for L293D

WORKING
• Numeric keypad is interfaced with port of the
microcontroller.
• LCD is used to show the entered password or all the
messages we want to show when entered password is
correct/wrong.
• Authorized user has to enter the security code using
zigbee.
• Controller check the entered password from the
password saved in it.
• If entered code is correct then user has to verify it
through keypad
• The password entered through keypad may be same
as entered through zigbee or may be different.
• When verification is done then motor start rotating
which represents the opening of door.

ADVANTAGE
• It provide more security as compared to the single stage security system
• It easy to use• Less circuit complexity• It based on new technology• Cheaper in cost
DISADVANTAGE
• Biometric security systems are more secure then this
system but they are also more costly
SOFTWARE REQUIRED
• Programmers Notepad [WinAVR]• Proteus 8 Professional• XCTU
