Highly Enhanced Safety & Security System in Helmet & Bike using Various Sensors with GSM Modules

This paper focuses on the eradication of road accidents by bikes and scooters & also enhances the safety & security of the bikes. A proficient method is proposed to decrease road accidents & enhance the security of the bikes by the usage of Alcohol Detection Sensor (MQ3) sensor & Fingerprint sensor. Mostly road accidents are due to the intake of alcohol by the drivers. To avoid this, MQ3 sensor is placed on the helmet to sense the alcohol content of the drivers. The MQ3 sensor monitors the blood alcohol content of the driver. The sensor continuously monitors the driver’s breath, and if alcohol is detected by the sensor, the driver can’t switch on the engine. Nowadays most of the bikes are hijacked while parked on the roadside. To mitigate this, a fingerprint sensor is placed on the bike, so that only the authorized person can switch on the bike. Therefore, it enhances the security of the bike. The MQ3 sensor & Fingerprint sensor are interfaced to engines using an Arduino Nano microcontroller along with a DC motor.
