The Automatic Breaking System utilizing a PIC micro controller aims to enhance vehicle safety by integrating multiple sensors and communication modules. This system employs an Alcohol Sensor to detect driver impairment, an Ultrasonic Sensor for proximity detection, and a Bluetooth Module for wireless communication. The core functionality revolves around monitoring the driver's condition and the vehicle's surroundings. Upon detecting alcohol levels beyond a predefined threshold or an imminent collision, the system activates DC motors to apply brakes automatically. Additionally, a GSM module sends alerts to predefined contacts in case of emergencies, while a Buzzer provides auditory warnings to the driver. This integrated approach not only improves road safety but also supports preventive measures against impaired driving, showcasing a significant advancement in automotive technology.
