Abstract: This project presents the development of an innovative smart transportation system using the Arduino Uno microcontroller, designed to enhance driver safety by monitoring heart attack symptoms and detecting alcohol consumption in real-time. The primary objective is to prevent accidents caused by health emergencies and impaired driving by implementing an automated emergency vehicle stop mechanism.
The system integrates a pulse sensor to continuously monitor the driver’s heart rate, detecting irregularities such as tachycardia (abnormally high heart rate) or bradycardia (abnormally low heart rate) that may indicate an impending heart attack. Concurrently, an MQ-3 alcohol sensor measures the driver’s breath alcohol concentration, identifying levels that exceed a predetermined threshold indicative of intoxication. Both sensors relay data to the Arduino Uno, which processes the information and triggers appropriate actions.
In the event of detecting an abnormal heart rate or high alcohol concentration, the system initiates multiple safety protocols. It activates an alert system, including a buzzer and an LCD display to notify the driver, and uses a GSM module to send emergency notifications, including the vehicle's current location, to predefined contacts such as emergency services or family members. Simultaneously, a relay module interfaced with the Arduino Uno controls a motor driver to safely bring the vehicle to a gradual stop, preventing sudden halts that could cause further hazards.
