Abstract: Car accidents are becoming more frequent, especially in remote areas where emergency help takes too long to arrive, leading to preventable injuries and deaths. To solve this problem, we developed an intelligent car safety system that automatically detects crashes and immediately calls for help. The system uses several smart sensors working together: impact sensors that feel when your car hits something, distance sensors that spot obstacles and blind spots around your vehicle, and GPS technology that knows exactly where you are at all times. When a crash happens, the system's built-in cell phone module automatically sends emergency text messages with your precise location to rescue services, helping ambulances and police find you much faster. The device is controlled by an Arduino computer chip and includes a small screen to display information, a buzzer for loud warning sounds, and Bluetooth capability for testing purposes. Think of it as a smart guardian angel for your car that works even in remote areas with poor cell service - the moment something goes wrong, it immediately alerts emergency responders with your exact location, potentially saving precious minutes that could mean the difference between life and death. This automatic response system is especially valuable when drivers are unconscious or unable to call for help themselves, ensuring that emergency assistance arrives as quickly as possible.
