This document proposes an IP-enabled digital door lock system for smart cities. The system would use a ZigBee wireless protocol to remotely control and monitor a digital door lock and connect it to various home automation devices. The door lock would act as a home server to securely control appliances and receive emergency notifications from sensors. It would operate in different modes like outgoing, incoming, and emergency modes and provide remote access and intelligent automation to improve home security and convenience.

3. INTRODUCTON
Concept of SMART CITY refers to the use of various Use of HYTEC technologies in
daily life
To transform current lifestyle in DIGITAL LIFESTYLE
To reduce efforts in manually handling of system.
For enhanced security with convenience and flexibility.
Remotely Tracking of activities.
“A smart city brings together technology, government and society to enable the following
characteristics: smart cities, a smart economy, smart mobility, a smart environment,
smart people, smart living, smart governance.”

4. Home Automation System
 Gives:
Remote/automatic control of things around home and much more.
An automated home is an intelligent home or interactive home that takes
care of mundane activities, leaving you enough time in indulging in other
activities.
Connecting various gadgets to the electronics equipments.

5. DIGITAL DOOR LOCK SYSTEM
Nowadays it is based on software zigBee ,a newly developed protocol for wireless
sensor.
Apart from inherent door security, this system also provide protection at home
against the different natural condition such as fire break out ,gas leakage and
similar calamities.
Apart from the service provided the best thing about this is ,
It’s a keyless system .

6. WHY ZIGBEE NETWORK ??
Extremely low cost
Easy implementation
Reliable data transfer
Short range operation
Very low power consumption
“SIMPLE BUT FLEXIBLE PROTOCOL.”

7. OPERATION OF SMART DIGITAL DOOR
LOCK:
The way how digital smart digital lock works
Works on two communication mode
 CENTRALIZED MODE
Takes the control of overall communication in the network and sensor mode acts
accordingly as door instructed .
 EMERGENCY MODE
Respective action is taken in all emergency situation……. Leaving of water for fir
etc and immediately that event is reported to the door lock without any initiation
from door lock.
Door lock in return reports the user through SMS or MMS.

8. MODES OF OPERATION
Modes of operation are of THREE types:
1)Outgoing Event : Door lock is last thing which user can do leaving the home.
Message will display on the screen.
2)Incoming Event: Give us flowchart of all incoming events
Eg .Entry of someone and user will receive message.
3)Emergency Mode: Activation of sensor during emergency, quick response through
sms.

10. ADVANTAGES
Communication
Cheap ,flexible and easily installed system.
No cabling or construction works
Intelligent locking system
Style , comfort & security

11. CONCLUSION
In this presentation I conclude a novel home automation system based
on ZigBee which is low rate of data transfer is about 250kbps. So this
ZigBee system is useful for Application that needs low data rate.
The proposed system exploits the Zigbee’s full capacity for monitoring
and controlling home environment and condition through the digital door
lock as the system is proposed on wireless sensor network.
