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 calculated by measuring the time difference between ultrasonic emission and return. DS18B20 is ud to detect the ambient temperature, 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.
