Car Overspeeding Detection System Is An Open source system. Basically its main function is to reduce overspeeding of cars by detecting its speed and reporting the overspeeding condition in the database.

Storage

Data of every overspeeding case is stored inside a MongoDB cluster which is very safe.

IoT

Data is sent through a NodeMCU i.e. An ESP8266 which is simple but effective.

Server

The backend server is hosted on repl.it for now, but it will be changed to heroku after the development is complete.

Language

The Backend server is coded in python while the system itself is coded in c++ (arduino language)

Hardware

The Data is sended with a NodeMCU (ESP8266) and the In-Car Components i.e. the buzzer, led's and LCD screen are controlled with an Arduino UNO

How It Works?

First of all the IR sensor detects the speed of the car. then it is processed in the Arduino UNO. If the speed is under limit, it will do nothing. But if the speed is exceeding the speed limit, it turns on the NodeMCU. the NodeMCU then gets the current latitude and longitude of the car with the help of a Neo6M GPS module. after that, it compares the lat. and lon. of the car with lat. and lon. of 10 police stations to find the police station having the shortest distance. after this, the latitude, the longitude, Car number, current date and current time is sent to the database under the particular police station with the help of the backend server.
