Zigbee Based Home Automation System

Wireless Sensor Networks (WSN) are made up of tiny sensing devices; capable of sensing some changes of incident/parameters and communicating with other devices, over a specific area. Mainly used for tracking, surveillance and environmental monitoring. These devices make it possible to be used in a system such as Home Automation and Security. Our purpose is to make our Home secure from any attacks physically and to the sensor network. Securing our Home starts from the outside, setting up a perimeter around house sensing intrusion and alerting the home owner. Allowing only predetermined users to enter the home. From the inside you can monitor for fires, leak, humidity or smoke, which the system will promptly report this to the owner as well as alert the proper authorities. Making most of the home voice controlled only recognized by the owner’s voice can add another layer of security.

An additional application of automation is called home automation. Home automation works by using advanced technology to control and do the jobs that people would normally do manually ("Home automation," 2010). The best and simplest way to install home automation is while a house is still being built. However, people who have houses already built can still have home automation installed through wireless

Having a home automation can go a long way in presenting your home as ‘smart home’. This is because most people nowadays have a smart-phone with them. However, just like other technology products, home automation cost varies from most affordable to extremely high cost.

Based on the organization, development, clarity, and concepts in the article “Really Smart Homes” by John Patrick Pullen, this article would receive a 90%.

There are many reasons to have a home security system installed. Your home, family and valuables will be protected from intruders, fires, carbon monoxide poisoning - in short - and most importantly, to give you peace of mind. A home security system may also save you money on your homeowners insurance policy!

Today, smart electronics are playing a central role in our daily lives and they deserve an even smarter role at home.

Home security systems is no longer a luxury but a necessity in todays high crime society. Burglary is a crime New Zealanders are most likely to suffer. Our solution to this problem is a smart home security application that would allow us to effectively and efficiently notify police and homeowners discretely, as well as accurately identify the stolen items. Thus, minimizing chances of a thief escaping conviction and ultimately reduce the annual burglary rate and provider safer homes.

This system also supports the use of Smart Home devices that RCR installs in its customers’ homes. Smart home devices are hardware that allows RCR customers use the Internet of Things to perform functions such as remotely turning on lights or AC units and receive automated alerts when certain this happen in the home. For example, if the garage is left open the owner can receive an alert that it was not closed. The Internet of Things is a term that is used to describe items that used the internet to perform any function.

Since a majority of these devices dwell in the home, and they can't have security software introduced on them, they are extremely helpless against assaults. With the surge of the IoT fever in the purchaser advertise, numerous makers are attempting to get their item to showcase rapidly, so now and again, security can be neglected. This is the place the home switch assumes a critical part. The switch is basically the section purpose of the Internet into your home. While the connected devices can't be ensured independent from anyone else, the switch can give insurance at the passage point. Albeit the present average switch provides some extra security, (for example, secret word assurance, firewalls, and the capacity to arrange them to just permit certain devices on your system), they don't accompany introduced security software. Which implies that malware can even now sneak through. With the notoriety of IoT devices, and the high vulnerabilities they convey, aggressors are as of now concentrating on approaches to misuse them. Along these lines it's critical that we advance beyond the terrible folks and keep them out of our homes. (3)

Figure 1 23 shows the proposed network arrangement between the nodes and their associated roles within the ZigBee network. The roles within the network are in accordance with the functionalities and requirements of each type of device as specified by the ZigBee networking standard. The PC/base station has been appointed the role of coordinator since its functions include hosting the SLAM and GUI processes. Therefore the PC/base station is required to transmit GUI data commands and receive updated sensor data to and from both quadcopters. Furthermore as these processes are computationally intensive and require a lot of memory resource; the PC/ base station must be mains powered; reinforcing the requirement for it to be a coordinator. The quadcopters have been appointed the role of routers so that they are able to relay data intended for the coordinator between each other, if one of the quadcopters should fall beyond the range of the coordinator. This would not have been possible if they were appointed the role of end devices. The quadcopters will be battery powered although the ZigBee standard for routers recommend that they be mains powered. Nevertheless, this recommendation was made out of preventing different network segments from falling if power to the router is lost. However this is not applicable in terms of this project as the routers will not be connected to any other network segments.

The next significant feature that consumers of tomorrow will expect from most products is ‘technology that brings forward simplicity through automation’. Their new range of TOUCH SWITCH will do just that. Simple touch function will facilitate multiple controls in terms of room lighting and mood. The switch will also be enabled with voice control to take the interaction to a whole new

Even common household devices such as refrigerators now have WiFi access. Thermostats also can be controlled via the internet now. As you can see, technology is ever evolving and growing. It doesn’t seem to be slowing down at all.

A ZigBee network is comprised of ZigBee nodes. Zigbee nodes are nothing but zigbee devices. A zigbee node mainly consists of three parts 1) microcontroller 2) transceiver 3) antenna. It makes use of stack profiles that are implemented by software. A zigbee node supports multiple subunits, every subunit posses an application object. The application object is used to describe the function of the sub

Abstract—Traditional environmental parameter monitoring system are either wired or those which are wireless and has less power consumption are for short range, and if they have long range capability then they consume a lot of power and are expensive. This paper has investigated in building a long range, low power and cheap wireless parameter monitoring system with functionality to send alert to the operator on increase of any parameter beyond a predefined limit.

The demand is increasing for automation, safety & control devices as users now demand more safe solutions. Demand for automation & sensing products is increasing even under difficult economic conditions in sheer volume terms.
