Nowadays, people are facing one of the most and biggest problems which is an accident. Most people are dying because of accidents. The death rate or even the smallest accident rate is increasing day by day. Traveling is an important part of life, whether it is a workplace or any other. The main reason for death recorded is due to the lack of unavailability of medical services at the accident. Another cause that i personally think is the lack of co-operation of people to follow signals. Practically thinking one cannot prevent or stop any kind of accident but can lower the post-trauma. In present days we can see that every single person may come across with accidents and this is one of the critical situations. Few people can survive and few people may lose their lives, which occurs due to lack of information. To overcome these problems, a black box came into existence. The main objective of the car black box using raspberry pi is to develop a hardware system that will monitor image and video, motion detection, humidity & temperature in real-time continuously on an SD card. So any input can be logged into memory so that any authenticated person can observe the specific data from any place (here from the same place too. The data is stored in the SD card that is externally connected to the Raspberry pi. The information is collected by Raspberry Pi processors using a camera module and other sensors which are connected to the raspberry pi which is Linux based operating system that will give all the collected data information to the monitoring system. The monitoring system will display the data (if needed and wanted) in real-time which helps the investigation to find out the scenario of the accident that occurred.
