This smart helmet system is designed to improve two-wheeler safety by addressing key risk factors such as intoxicated driving, failure to wear a helmet, and exposure to extreme internal temperatures. The system ensures that the rider is wearing a helmet through a built-in sensing mechanism and detects alcohol consumption using an MQ3 sensor. By analysing the analogue output of the sensor, the system can distinguish different levels of alcohol concentration and respond accordingly. Additionally, a tilt sensor enables fall detection, which triggers an automatic alert via GSM, sending the rider's location to registered contacts in the event of an accident. The helmet also incorporates a Bluetooth module, facilitating hands-free communication without requiring helmet removal. Furthermore, an integrated DHT11 temperature sensor monitors internal temperature conditions. If the temperature exceeds a predetermined threshold, an LED inside the helmet is activated as a warning. Should the LED remain on for over an hour, a buzzer is triggered to alert the rider to take a break and allow the temperature to drop, reducing the risk of heat-related health issues. The system ensures that if the helmet is not worn or if alcohol levels exceed the permissible limit, the vehicle's engine remains disabled. Through these combined features, this smart helmet system aims to enhance road safety, minimize accident risks, and improve rider protection and comfort.
