Abstract

An embedded system is an application-oriented special computer system which is scalable on both software and hardware. It can satisfy the strict requirement of functionality, reliability, cost, volume, and power consumption of the particular application. Embedded systems in many cases must be optimized for life-cycle and business-driven factors - rather than for maximum computing throughput. In this project, a system with smart controlling and auto emergency features is proposed. In this system, the user can control the appliance at building, such as light and fan, which can reduce the energy wastage. On the other hand, the automatic emergency system has the features which the user can report the emergency situation in the building instantly to the authorities and contacts by using calling button and emergency message in the android application. Moreover, address location are also shown in the application on the android phone and the user can use the application to display the maps of the location. By knowing the location of the user, this could also help in locating the elderly people. In developing the smart controller and automatic emergency system, microcontroller Arduino-Uno has been used. MIT app Inventor 2 has been used as the designer application for developing the application for android mobile phone. Instead of hungry force WiFi association, the Bluetooth connection is utilized. The security of the communication is also guaranteed within the building. A prototype has been developed. The prototype demonstrates that the controlling system such as LED and fan can be turned on using the android mobile phone, the flame sensor can detect the flame in range of 1OOcm approximately, and the buzzer are ring when the flame is detected. On the other hand, in emergency situation, the developed system demonstrates that with a single button, the user can make an instant calling or messaging with the information of current location in maps format and coordinate. In summary, this project shows a good feature for industrial needed, as there are lots of houses and building nowadays, which is hard to monitor and to control. The developed system is low-cost, easy to program, easy to assemble, and low power consumption which is also user friendly system, meeting the demands of the customer nowadays.
