| Abstract: | The principle of ultrasonic distance measurement is presented. Ultrasonic sensors is used as the core device, and method of temperature compensation is introduced to realize the accurate measurement of distance from 5 centimeters to 4 meters. The system consists of STC89C52 single chip, DSI8B20 temperature sensor, HC -SR04 ultrasonic sensor and digit- al display circuit. Test results show that the measurement error of the system is less than 3 centimeters. Because of its simple structure of hardware,low cost and reliable performance, the system has certain practical value . |
