| Abstract: | This design is a sort of system which is used for measuring distance by ultrasonic. It uses micro controller AT89S8252 as its primarily control chip. It has the functions such as the automatic redeem, the voice broadcasting and dis- play in Chinese. This system measures distance by pulse echo , measures temperature with temperature sensor DS18B20 and compensats the measuring error which result from temperature with software programs. |
