ABSTRACT
Home Automation in reduces the need for direct human intervention when it comes to managing home appliances and lightnings. The benefits of a home is numerous and it is normally design to meet the user’s requirement. Home automation devices can be installed for the purpose of managing all of your home devices from one place, to give a remote control access of home functions, maximize home security or increase energy efficiency.The aim of this work is to design and implement a prototype which depicts a miniaturized version of a smart home with some specific automation features.
A micro-controller is used at the heart of this system. The controller unit receives signals from the users input interface both the remote (Phone App, via Wi-Fi module) and locally (via the keypad terminal) and processes these signals, it then switches on/off the required lighting point or locks/opens the required door. A proximity sensor is used to detect when there is a security breach and will send signals to the control unit in the event of such occurrence. The Control unit will lock all doors and notify the user’s phone via the Wi-Fi module. An infrared sensor is used to detect intrusion in the premises around the home, it signals the control unit to turn of lights and sockets, and the aim of this is to create awareness and minimize energy wastage.
The android app designed for this work is tested for connectivity and responsiveness, the control switches were used to switch ON/OFF lights on the prototype house. The response time for the lights to come ON/OFF varied due to variations in network connection speed.
