Zigbee based Smart Home Automation Under the guidence of:- By:- Er.Priyadarshni Ashish Kumar Univ Roll No

Outline of this presentation:- Need of new technology. Zigbee. A brief comparison with other existing technologies. Applications. Smart Home Automation :-Architecture and implementation in our day to day life.

Zigbee a low-cost, low-power, wireless networking standard Based on IEEE operates in the radio bands Low data rate (approx 250 Kbit/s) Range of operation - 30 to 100 m

Other technologies and its need :- Standard Bandwidth Power Consumption Protocol Stack Size Stronghold Applications Wi-Fi Up to 54Mbps 400mw100+KB High data rate Internet browsing, PC networking, file transfers Bluetooth 1Mbps 40mw100+KBInteroperability, cable replacement Wireless USB, handset, headset ZigBee 250kbps30mw32KBLong battery life, low cost Remote control, battery- operated products, sensors

Some related points… Two modes –Beacon,non beacon Device Types- ◦ Full Fuction Device ◦ Reduced Function Device Security Encryption,access control,frame integrity. Channel Access –CSMA/CD

Zigbee protocol stack

Layers :- Application Support Network IEEE (PHY) IEEE (MAC)

Application :- Home Automation  Anything that gives remote or automatic control of things around the home. Smart Energy Telecom application Personal Home.

Existing Technologies :- Java based system Bluetooth Phone based system IEEE 1394 based system

Analysis of the Existing Systems Complex and expensive architecture Lack of network interoperability Interface inflexibility Security and safety

Features of the proposed system Reduced Complexity Low cost Flexible Variety of controls Remote monitor and control Secure and Safe

System Architecture

Home Gateway Consists of Wi-Fi module, ZigBee Microcontroller and power supply Primary Function - Data translation services between the internet, Wi-Fi and ZigBee networks. Real time control and monitoring of devices using device database Flexible control modes

Virtual Home Flow Chart

Network ▫ Uses Mesh topology- to overcome a disconnection due to obstacles

ZDO:- ◦ Genric Devices  On/Off Switch  Level Control Switch ◦ Range Extender-Router. ◦ Remote Control. ◦ Lighting Devices.  On/Off Light  Occupancy Sensing Cluster Support  Dimmable Light ◦ Closure Device-Shade. ◦ Heating Cooling Devices.

System Initialization/ implementation Network initialization phase ▫ Scans all available radio channels ▫ Assign MAC address for all devices in the network Wi-Fi connection through DSL modem router Home Gateway connects with ZigBee and Wi-Fi network Input to Home Gateway can be either from Wi-Fi or ZigBee network

Continued…. Startup Attributes Set :-Interoperability. Join perameters as Scan attempt,Time between scans,Rejoin Interval,Max.Rejoin Interval. End Device perameters :-Indirect poll rate. Cluster and commissioning.

Conclusion Identified the problems of existing home automation systems Solved the problem of network interoperability A low cost,flexible and secure system is proposed
