Design of a Vehicular Emergency Intercom System Using Electronic Circuits and Sensors

This study presents the design of a vehicular emergency intercom system aimed at improving motorcyclist safety through the integration of electronic circuits and sensors. The system employs an Arduino UNO R3 microcontroller, GSM SIM900L modules, and ultrasonic and proximity sensors. It is programmed in C++ to detect falls and automatically trigger alerts with high efficiency. Falls can be detected with 95% accuracy within a range of 2 to 100 cm, with an average response time of 1.2 seconds,making it suitable for emergencies. The system's ability to send alerts quickly enhances user safety in critical situations occurring at distances between 101 and 150 cm. However, limitations in the detection range were identified, particularly at minimum distances between 0.02 cm and 1.96 cm and maximum distances between 151.36 cm and 177.72 cm, which fall outside the operational range. This suggests the need for future adjustments. This project offers an innovative, efficient, and easy-to-implement solution for improving road safety, featuring high sensitivity to optimize emergency response.
