IOT BASED SMART HELMET WITH BIKE SECURITY

Abstract

The objective of this paper is to address the safety concerns that parents have when their child is riding a two-wheeler. To achieve this, this topic includes two units, the Helmet Unit (HU) and the Motorbike Unit (MU), which communicate with each other via radio frequency. The HU is equipped with sensors that measure the rider's pulse rate, alcohol content in their breath, and intensity of vibration. The pulse rate sensor detects whether the rider is wearing the helmet or not. The MU has a GPS and GSM module that sends location messages to emergency contacts in case of an accident. The accelerometer on both units detects accidents, and the MU's sensor ensures that the rider is sitting correctly, driving safely, and not over sspeeding. If the alcohol level is too high or an accident is detected, the MU turns off the ignition, sends an emergency message with location, and displays emergency contact details on the OLED screen. A rider safe push button is also provided. The LIDAR sensor on the MU alerts the rider of vehicles approaching from behind. Force-sensitive resistors are installed on the handle grip and footrest to ensure proper seating. The accelerometer in the MU detects tilt along different axes, and if it exceeds the threshold, the buzzer starts beeping and a safety message is displayed on OLED. Finally, the MU's ESP8266 Wi-Fi module sends bike speed and tilt information to the Thing Speak server, which allows parents to monitor their child's safety.
