WEEK 6

WEEK 6 : Benchmarks For Final Year Project

Objective :

1) To find out various ways to control home automation system.
2) To identify the advantages and disadvantages in every way used.

Methodology :

1) Find information on projects that have been done on the internet.
2) See the advantages and disadvantages of each project.
3) List 3 ways to control home automation system that people usually make for their projects.
4) Make a comparison between 3 projects.

Results :

Analysis & Discussion :
I have found 3 ways to control home automation system :

1) Android

Android application meaning we have a smartphone which has got the android operating system and one we switch on the button the bulb will on. There is a pro and cons in this project which is for the pro, it can save cost because the apps that need to be used are free.Besides, many people nowadays use android phones, so this makes it easy for the project maker. The apps also are more attractive and have multiple function. For the cons, it required internet access, so the apps are always working.

2) Global System for Mobile (GSM)

In this project, GSM wireless communication is used for controlling home appliances. It send some commands for controlling AC home appliances. After receiving given commands by Arduino through GSM , Arduino send signal to relays, to switch ON or OFF the home appliances using a relay driver. There is pro and cons which is for the pro it can make calls and send short messages. For the cons, it requires credit to make calls and send messages, thus requiring a lot of spending. Besides, has limited functionality.

 3) Bluetooth

In this project, it use step down transformer and then Arduino Uno R3 connected to the bluetooth module. After that, it use 4 relay connected to 3 bulbs AC bulb and another relay connected to DC fan. There is pro and cons which is for the pro it do not require internet data. By using bluetooth, it will saving cost because it does not require credit to get function but the distance required for the bluetooth to work is very minimal - only 10 to 15 meters.

Conclusion :
I have learnt a lot of things through comparison between projects so that from that I can make a better project and improve the deficiencies in the project.
