| Abstract: | This paper is based on the working principle of the ultrasonic range finder of car reversing system controlled by single - chip microcomputer. It uses the single - chipped ultrasonic ranging module HC - SR04 in order to transmit and receive ultrasonic and detects temperature through the DSI8B20 temperature sensor so as to compensate the influence of temperature on ultrasonic speed. Combining with the peripheral circuit module, this paper realizes the display and alarm of temperature and distance. On the basis of the system hardware design, the system software is designed. |
