Wireless Black Box Using Rasberry Pi


Nowadays, traffic accidents are one of the main reasons of fatalities in the world, many lives can be saved by reducing the time between the occurrence of an accident and the arrival of first help at its location. In research literature, numerous accident detection and notification systems were proposed to solve this problem. Including built-in unit, black-box, and mobile phone based solutions. Our research has been devoted to design a black-box system that integrates IOT and Global Positioning System (GPS) technologies to locate and send a Minimum Set of Data (MSD) containing important information about the accident collected using different sensors such as the accident type, longitude and latitude, time and speed of the vehicle to the emergency services (Hospitals, civil protection, and police). This system is developed based on the Raspberry Pi 3 in order to provide both low cost and high system performances.


In present situation any accident occurs the information about an accident is needed to find out the cause of the accident. In this case the investigators should know about the accident at that time the Black box is more useful. Then the investigators should easily know about the accident. In case of any accident occurs immediately location and message should be sent to the ambulance and rescue team. Then they should easily know about the accident. The information about the accident is gathered from Black box. It can store information about the vehicle and surrounding images also. Previously it can be used in Helicopters and Airplanes. Now we are trying to implement it in our own vehicles. If any accident occurs, then message will send to the provided mobile numbers. Various sensors are used to build the black box in order to find the speed of the vehicle, pressure and angle detection. If angle of vehicle will be changed then the sensor will detect the accident immediately motor will stop. It continuously records the information like speed of the vehicle, sensor values surrounding images and stores in the internal memory. Various sensors are used to build the black box in order to find the speed of the vehicle, pressure and angle detection. If angle of vehicle will be changed then the sensor will detect the accident immediately motor will stop.

Existing system

  • Post-Accident Detection Systems.
  • Lack of Intelligence in the detection systems.
  • Fails to track the collision and pre-damage status.


  • Uses internet for alert.
  • Accuracy is low.
  • Limited since it needs a manual button to reduce faulty notification.

Proposed system

In this project the Black Box is trying to implement in vehicles. The vehicles should have Black Box system so, that when an accident occurs the information should be stored in that system. The sensors can detect the accidents and sometimes it should avoid the accidents. In this we are using IOT functionality then by using internet also we can able to share the data.


  • GPS tracking is easy and very fast.
  • The vehicle number and persons contact number will be transferred to police control room is immediately.
  • Locking systems are automatic.

In this proposed device, Wireless black box is basically a device that will indicate all the parameters of a vehicle crash and will also store and display its parameters at every three seconds such as date, time, IR, MEMS, location, vibration, alcohol limit etc. At the time of accident, the message will be sent from the system built inside the car to the registered mobile numbers such as IOT Technology of police stations, hospitals, family members, owner etc. We have used various types of sensors like Vibration sensor measures vibrations felt by the car during accident. Alcohol sensors are located on the steering wheel which will indicate whether the driver is drunk. Accident occurs at that time if any angle changes that will be detected by MEMS sensor. Distance between two vehicles is less than the minimum distance then the Ultrasonic sensor will detect it.IR sensor is connected to the car in the wheel part to measure the speed of the car as in a sim

ple manner. All the parameters sensed by the sensors will send the signal to Raspberry pi. If any accident occurs sensor will detect it and IOT functionality for sending the GPS latitude and longitude values.
