SmartGuard: IoT-based real-realtime intrusion detection using active and passive infrared sensors with alert notification via Telegram application

The SmartGuard prototype is an innovative IoT-based real-time intrusion detection system designed to enhance home security using active and passive infrared sensors. This prototype utilizes the NodeMCU ESP8266 platform and leverages the Telegram application to deliver instant alert notifications to users. The primary objective of the project is to develop a reliable and efficient home security system that detects and notifies users about potential intrusions in real time. The functionality of the SmartGuard prototype is thoroughly evaluated through comprehensive testing methods, including functionality testing, network testing, and usability testing. Functionality testing focuses on assessing the prototype's ability to detect different objects accurately, while network testing analyses the system's performance regarding response time and reliability. Usability testing involves gathering user feedback to evaluate the ease of use, security features, and overall user experience. Results from the testing phase demonstrate the prototype's effectiveness in detecting intruders and promptly notifying users through the Telegram application. The prototype exhibits reliable functionality, with the ability to distinguish between humans, animals, and other objects, thereby minimizing false alarms. However, certain limitations are identified, including the susceptibility of the infrared sensors to motion and the limited detection range of the active infrared sensor. In conclusion, the SmartGuard prototype showcases the potential of IoT technology in revolutionizing home security systems. By leveraging active and passive infrared sensors and the Telegram application, this prototype offers users real-time intrusion detection and prompt notifications, contributing to an enhanced sense of security and peace of mind for homeowners.
