Nevon Car Accident & Alcohol Detector & Recorder Blackbox


Consistently the existences of roughly 1.3 million individuals are cut short because of a road traffic crash. Somewhere in the range of 20 and 50 million additional individuals experience non-fatal injuries, with many causing a disability because of their physical issue.

Road traffic injuries make high economic losses for people, their families, and to countries in general. These misfortunes emerge from the expense of treatment as well as lost efficiency for those killed or crippled by their injuries, and for family individuals who need to get some much needed rest work or school to really focus on the harmed. Road traffic crashes cost most nations 3% of their GDP.

So here we design a system that can alert the vehicle owner/loved ones over sms as soon as any signs of accident or may lead to an accident are detected. As well as the system stores all readings that lead and happened during the accident so that investigators may study exact causes of accident to avoid further such instances.

This System provides the following advantages:

  • Instant data Capture from Sensors
  • Instant SMS alert for Drunk Driving Detection
  • Instant SMS Alert for Fire or Accident Detection
  • Accident Data Storage for Investigation

The system makes use of Temperature sensor for fire detection in car, Vibration sensor to detect any impact force or heavy vibrations, Alcohol sensor to check if driver was drunk, gyro scope sensor to record data if vehicle tilted or turned over during accident and a GPS and GSM modem to send SMS with GPS Coordinates about the incident. This complete system is now powered by an Arduino Mega to operate the system.

The system also has 2 Motors used to demonstrate as car engine. We can increase the speed of Motors using Trimpot. As we increase the speed beyond set limit, the system detects over speeding and sends an SMS Message with over speeding alert and GPS coordinates to registered number. The system monitors all sensor data to check for any abnormalities. If the fire sensor detects a fire, the controller operates the interfaced GSM modem to send an SMS to the registered contact number informing about the event and also starts recording data.

Similarly if the vibration sensor detects heavy vibrations, the controller sends SMS to registered number informing about the event to the registered user. Is alcohol sensor is triggered the controller similarly sends an SMS notification with alcohol data and GPS Coordinates on Map link for easy vehicle location tracking. In case of any sensor triggers an abnormal activity the black box starts storing all sensor data on a second by second basis in an SD card so that investigation team may recover the data and study exactly what went on during the accident.
