Abstract

With the rapid development of technologies, the Internet of Things (IoT) has been introduced to help users in everyday activities with the aid of the Internet. IoT can be applied to home security systems due to the increasing case of burglary. It’s a necessity to enhance home security due to the rise of attempted break-ins. Nowadays, cheaper security systems do exist but they still lack performance. Besides that, some home security uses incompetent and inadequate tools. Lastly, the lack of demand and attention towards security systems due to the cost. For this project, three objectives need to be achieved. First, design a home security system that will display the time of the intrusion. Second, the study of the reaction time of the system to send a notification. Third, analyse the suitable distance for the PIR Sensor to optimise the system functionality. In this project, the idea of developing an IoT-based home security system is to reduce the number of home intrusions. This system will use components such as an Arduino Uno, Arduino ESPWiFi Shield, three PIR Sensors, Buzzer, and a Lamp. The Arduino Uno will be the microcontroller of the project. The Blynk application will be used as the IoT platform. The system connects to the Wi-Fi by using Arduino ESPWiFi Shield. Three PIR Sensors will be used to detect motions and each will be placed near three-door. Whenever one of the PIR Sensors detects the door opening, it will send a notification through the user’s smartphone. Not only that, the Buzzer will produce sound and the outside Lamp will be turned on. For the outcomes of the project, the system can allow the user to know when the intrusion happened. Moreover, some experiments will be conducted to study the reaction time of the system to send a notification and to analyse the suitable distance for the PIR Sensor to optimise the system functionality. In a conclusion, this project can reduce the number of home intrusions with the aid of IoT.
