The project presents an Internet of Things (IoT)-based home security system utilizing ESP-32, ESP-32 Camera, Keypad, LDR, Laser, PIR Sensor, and a Buzzer. The system aims to enhance home security by integrating various sensors to detect motion and unauthorized access, providing real-time alerts and notifications. The PIR Motion Sensor detects movement in the monitored area and triggers a buzzer alert to notify of potential intruders. The Laser Sensor serves as a tripwire, where any interruption in the laser beam by a person crossing it also activates a buzzer, ensuring an immediate response to unauthorized access attempts. Additionally, the system incorporates a Keypad for password-based access control. If an incorrect password is entered, the ESP-32 Camera captures a photograph of the intruder and sends it as an image via Telegram to a predefined user, allowing for real-time monitoring. The LDR (Light Dependent Resistor) detects light levels to support the functionality of other components, potentially triggering events under certain lighting conditions. The Buzzer plays a critical role in alerting the user to any security breach, whether it’s a motion detected by PIR or a tripwire interruption by the laser sensor. This integrated system provides a robust, reliable, and easily deployable security solution for home automation and surveillance.
