基于STM32的超声波测速测距系统设计
Design of ultrasonic velocity and range measurement system based on STM32
摘要
Abstract
The system takes the STM32 processor as its control core,and mainly includes ultrasonic transmitting circuit, ultrasonic receiving circuit,temperature compensation module and liquid crystal display circuit. The distance and speed are cal⁃culated by measuring the time difference between ultrasonic emission and return. DS18B20 is used to detect the ambient temper⁃ature,and correct the ultrasonic propagation velocity error. The testing results show the system can measure the distance within 5 m and speed in 100 cm/s.关键词
