Investigation of current technologies in smart house systems

This thesis is aimed at readers who have basic technical and engineering background. It would be helpful to have basic knowledge of programming, networking and security concepts that are very important for presenting different features of Smart Houses. It is also assumed that readers are familiar with the various home technologies used in homes today. Home automation involves introducing a degree of computerized or automatic control to certain electrical and electronic systems in a building. A hardware system is installed to monitor and control the various appliances. The system would control the appliances based on its configuration. For example, it could automatically turn on the lights at a specified time in the evening, or it could measure the ambient light using a hardware sensor and turn on the lights when it grows dark. For example, one could turn on the air conditioning from the office, before leaving for home. This project demonstrates a simple home automation system that allows the user to control it with a wireless device such as a Bluetooth enabled mobile phone. The system allows the user to control each of the lights and fans individually. It can automatically turn off the main lights and turn on a night lamp at a specified time. By measuring the signal strength, it can detect when the user enters a room and automatically turn on the light and fans, and then automatically turn them off when the user leaves the room. Automation system achieved great popularity in the last decades and it increases the comfort and quality of life. In this paper an overview of current and emerging home automation systems is discussed. Nowadays most home automation systems consist of a smartphone and microcontroller. A smart phone application is used to control and monitor the home appliances using different type of communication techniques. In this paper the working principle of different type of wireless communication techniques such as ZigBee, Wi-Fi, Bluetooth, EnOcean and GSM are studied and their features are compared with each other so the users can choose their own choice of technology to build home automation system. Moreover in this research work the survey of different home automation systems is discussed and their advantages and drawbacks are also highlighted There will be a system that allows you to activate / deactivate the alarm system and receive status information with any smartphone with internet access. Fire alarm system support through smoke sensors will be a safe home environment, preventing poisoning and explosion based on this. Damage to our own homes and subordinate neighbors will be prevented by water flood detection and prevention system with water discharge sensors. Detecting and preventing gas leaks with carbon monoxide sensors Early intervention will save lives due to emergency call initiation with panic button support. Automated precaution will be taken by automation of cutting water or gas flow automatically in case of any leakage.
