IoT-Enabled Smart Helmet for Bike Safety

ABSTRACT - Motorcycle accidents are often caused by riders neglecting safety measures, such as not wearing helmets, riding under alcohol, or using mobile phones. We propose a Smart Helmet System integrated with IoT and wireless communication to address this issue to enforce rider safety. The system consists of a helmet unit and a bike unit. The helmet has sensors to detect helmet usage, alcohol consumption, and mobile phone activity. If any violation is detected, the bike’s ignition remains disabled. Additionally, if the rider removes the helmet, drinks alcohol, or uses a phone mid-ride, a continuous buzzer alert is triggered until compliance is restored. The system operates without cloud dependency, using Bluetooth (HC-05) for real-time communication. It is cost-effective, easy to implement, and suitable for both urban and rural areas. This automated safety solution helps reduce accidents by ensuring compliance with road safety regulations. KEYWORDS - Helmet, Bike, Arduino, IR Sensor, Bluetooth, Relay, Alcohol Sensor, EMF Sensor.
