Abstract
Smart homes are thought of as places where people live in where there are devices and physical objects connected to the internet, featuring intelligent technology which is able to simplify everyday activities. The objectives of this project are to measure the response time and efficiency, and to enhance the capabilities of the smart home system. The project makes use of two units of the Raspberry Pi 3 Model B+, four sensors and LEDs, to represent home appliances. OpenCV is used for accurate detection of intruders and a camera is used to live stream the home. The user interface is an Android application where the user is able to monitor and control the home appliances, view the live streaming, and receive notifications should an intruder be detected in the home. For the first objective, the measurement of the response time was carried out in four different situations, namely during monitoring of appliances, control of appliances, launching the live stream and receipt of notification in the smartphone. The response of the monitoring of appliance was found to be the best performing one out of the four, at an average of 0.1648 s, while the slowest response was found to be the launch of the live stream in the application, at an average of 6.2 s. As for the second objective, the number of smart home features in the system was counted to check if all the criteria of a smart home are satisfied, and it is found to satisfy all five of the criteria. Hence, these findings are hoped to suffice as reference to future researchers who would like to improve the system.
