Nowadays, vehicular accidents have been increasing from day to day. Most of them are the cause of over speeding. This thesis describes the Arduino based vehicle speed detection system using Doppler radar. The primary goal of this system is to design of the vehicle speed detector using Doppler radar which is used to reduce the amount of accidents caused by over speeding. In this system, continuous wave CW Doppler radar which is a special case that only provides a velocity output is used as a sensor and the microcontroller is used to calculate the speed of the vehicle. Moreover, the amplifier is used to amplify the voltage level to drive the microcontroller as the sensor output is in micro volts. It is also included LCD display to indicate the speed level. A Doppler radar that can determine the frequency shift that occurs in electromagnetic waves due to the motion of scatters toward or away from the observer through measurement of the phase change that occurs in electromagnetic waves during a series of pulses. The Doppler frequency is negative for objects receding from the radar. The Doppler frequency is positive for objects approaching the radar. This system can be acceptable in real time applications because it is independent of temperature, humidity, noise airflow, dust, light, etc. The results of design are tested and follow through realization. Each of the implementation is evaluated and these evaluations lead to the conclusion that the design is able to achieve high accuracy of the speed. The major components of the design are Doppler radar HB100 , Arduino Uno, LCD display and LM324. C programming language is developed in this system. The results of this work can improve the performance of automobile safety system.
