“Alertix – Portable Door Intrusion Detection and Alert System” is an intelligent and portable security solution designed to provide real-time intrusion detection and alert mechanisms for homes, offices, hostels, shops, and temporary setups. The system uses the IndusBoard Coin V2 integrated with an ESP32 microcontroller, built-in 3-axis accelerometer, GSM A7672S communication module, and C4001 mmWave presence sensor to detect unauthorized access, vibration, and human presence near doors. When abnormal vibrations or intrusion activities are detected, the system analyzes the sensor data using predefined threshold logic and immediately activates a buzzer while sending alert notifications to the user through GSM-based SMS or phone calls. Unlike conventional security systems that depend heavily on Wi-Fi connectivity, cloud services, or expensive installation procedures, Alertix operates independently using GSM communication and a rechargeable battery-powered architecture, ensuring continuous operation even during power failures or in low-network environments. The inclusion of vibration sensing and mmWave radar technology enables early intrusion detection before forced entry occurs, improving security reliability and reducing response time. The proposed system is compact, energy-efficient, cost-effective, and easy to install, making it suitable for portable and standalone security applications. The project demonstrates how embedded systems, IoT concepts, and wireless communication technologies can be integrated to develop an affordable and reliable smart security solution for modern intrusion detection systems.
