Vehicle Mishap Prevention and Detection using IOT and mesh topology implied node to node Communication

The emerging trend of automobile connectivity with and without internet in accordance with the radical growth of traffic, technologies should be appropriate to solve the issues related to speeding negligence of the driver, instant recovery of the accident-prone vehicle and causality within the golden window time. One of the challenges encountered in the recovery and timely assistance, is time of the incident and scare population. This article elaborates on a hybrid technique incorporating state of the art technology to detect and prevent traffic and automobile mishap. This is achieved by interface Hall effect magnetic sensor to detect the speeding, MQ2 gas sensor to keep a count of the oxygen level comfortable frequency, added on objective is the flame sensor to identify and caution the driver and the authorized personnel in case of fire in order to prevent disaster. Accelerometer MMA 7761 is incorporated in the model to identify the axis tilt, Piezoelectric sensor acts as a safety device, on occurrence of an accident, the enormous strain endured is converted to an electrical signal which symbolizes accurate of an incident. To maintain the safety distance between the vehicles, an ultrasonic sensor is installed to indicate any violation and thereby preventing the collision which tend to happen unexpectedly. A prototype is made incorporating all the sensors with Arduino, Wi-fi module microcontroller and the information collected is transferred to cloud which is accessible universally through all modes.
