Abstract

A safety driving warning system which can use Ultrasonic wave to measure the distance and generate an early warning of dangerous distance has been designed in order to improve driving safety by the propagation velocity of ultrasonic wave in the air soon, less energy consumption, directional well. STC89C52 MCU is employed as the key control unit; HC-SR04 ultrasonic module is utilized to complete ranging and speed detection; and temperature sensors are used to reduce the influence of temperature in sonic ware; Through displaying the measured speed, distance, and in the display module of LCD 1602 screen, the speed and distance will be measured and compared so as to improve measurement precision; when the distance is less than security distance, the buzzer will utter an alarm to remind the driver to react properly.
