This project presents an Internet of Things (IoT)-based home security system utilizing ESP-32, ESP-32 Camera, Fingerprint Sensor, LDR, Laser, PIR Sensor, and a Buzzer. The system aims to enhance home security by integrating various sensors to detect motion and unauthorized access while providing real-time alerts and notifications. The PIR Motion Sensor detects movement in the monitored area and triggers a buzzer to notify occupants of potential intruders. A Laser Sensor functions as a tripwire, activating the buzzer if its beam is interrupted, ensuring immediate detection of unauthorized entry.

Access control is managed using a Fingerprint Sensor, allowing only authorized individuals to gain entry. If an unauthorized fingerprint is detected, the ESP-32 Camera captures an image of the person and sends it via email to a predefined user, enabling remote monitoring and prompt response. The LDR (Light Dependent Resistor) detects ambient light levels, helping to automate responses under specific lighting conditions. The Buzzer serves as a primary alert mechanism for all detected security breaches.

This integrated system offers a reliable, smart, and efficient solution for home security, combining biometric access control with real-time surveillance and email-based alert capabilities.
