We hereby present an advanced road vehicle safety device. The device tackles the problem of loss of lives, arising from late medical attention to care for accident victims after an accident as a solution that enables fast response to persons involved in ghastly vehicle accidents. It uses ultrasonic sensor to detect the changes in the body of the vehicle due to a mechanical impact from an accident and sends a signal to the microcontroller which is connected to a buzzer. The buzzer in response to the signal triggers an alarm and simultaneously a Short Message Service (SMS) and recorded phone call are sent to registered contacts in the device. Arduino ATMega328P microcontroller monitors and activates the system when there is impact detected by the ultrasonic sensor. Then the buzzer outputs the warning sound to alert while the Global System for Mobile communication (GSM) module sends SMS alert and places a call when there is significant impact on the vehicle. This device senses any Izod Impact causing up to 10cm penetration at the impact zone of the vehicle. The system has a response time of 0-3 seconds for activation of the buzzer and 5-10 seconds for the GSM module.
