The Laser Home Security system is designed to enhance home security by detecting intrusions and sending email alerts to a smart mobile device. The system utilizes an ESP32-CAM microcontroller, a transistor, a laser, an LDR (Light Dependent Resistor), a buzzer, and email alert functionality. The system works by emitting a laser beam across an area to be monitored, with the LDR positioned to detect the laser light. When an intrusion is detected, causing the laser beam to be interrupted, the LDR's resistance changes, triggering the transistor to activate the ESP32-CAM. The ESP32-CAM captures an image or video of the intruder and sends an email alert to the user's smart mobile device. The email alert includes the captured image or video, providing visual confirmation of the intrusion. Additionally, a buzzer is activated to alert nearby individuals of the intrusion. This system offers a cost-effective and efficient way to enhance home security, providing real-time alerts and visual evidence of intrusions to help ensure the safety and security of the home and its occupants.        

Objectives:

• To develop a laser-based home security system for detecting unauthorized intrusions.
• To use a laser and LDR sensor to detect interruptions in the laser beam.
• To use the ESP32-CAM to capture images of detected intruders.
• To send real-time email alerts with captured images to the user's mobile device.
• To activate a buzzer to alert nearby people during an intrusion.
• To provide a cost-effective, reliable, and efficient home security solution.
