A SMART HELMET TO DETECT ANOMALIES OF ITS USERS AND ENVIRONMENT

Abstract

The Smart Helmet is an intelligent device that can tell if a person is wearing a helmet and if they are driving with non-alcoholic breath. In this case, we have a transmitter on the helmet and a receiver on the bike. A switch ensures that the helmet is always on the user’s head. The ON state of the switch guarantees that the helmet is correctly placed. Alcohol sensors are installed near the rider's mouth; if any of these conditions are not met, then the engine can't start. If the rider is involved in an accident and the helmet is thrown to the ground, then the alcohol sensor detects this and activates the GSM Module, which automatically contacts a family member. It is our main goal to make it easier for motorcycle riders to see on the road. Ultrasonic sensors and a vibrator motor in the new system can measure the necessary distances between passing motorcycles and the vehicle in the rear. The system will alert the rider through the vibrator motor, LEDs, and buzzer that are installed on their helmet as a warning to them about the range of insecurity that the ultrasonic sensor detects. Arduino UNO was used as the system's primary processing unit to manage all the system's networking elements. Arduino UNO put in front of the rider and displays the distance detected by the ultrasonic sensor using OLED displays. Data transmitted by the ultrasonic sensor will be wirelessly transferred to the helmet node, which serves as a reception unit, using the wireless transceiver module.
