Smart Vehicle Headlight Auto Switching and Intensity Control

The Smart Vehicle Headlight Auto Switching and Intensity Control system is an advanced safety and automation solution designed to improve both visibility and overall driving experience. It intelligently manages the vehicle's headlight operation by automatically adjusting brightness according to surrounding light conditions using an LDR (Light Dependent Resistor) sensor. This feature ensures that the headlights provide optimal illumination during low-light conditions, such as at night or in tunnels. Alongside this, an ultrasonic sensor is integrated to detect nearby obstacles, warning the driver with an audible alert via a buzzer, thereby reducing the chances of collisions in real-time scenarios. To further enhance safety, the system incorporates a MEMS (Micro-Electro-Mechanical Systems) sensor that identifies sudden impacts or tilts associated with accidents. Once an accident is detected, a GSM module sends immediate notifications, while GPS functionality is employed to provide precise location data, ensuring timely assistance in emergencies. All operations are coordinated by an Arduino microcontroller, which processes sensor data and displays critical information on an LCD screen for driver awareness. By combining smart lighting control, obstacle detection, accident monitoring, and emergency communication, this system presents a robust and efficient approach to modern vehicle safety and automation.
