| Abstract: | A high-precision non-contact ultrasonic ranging system was designed with C8051F020 in this paper.Four HC-SR04 ultrasonic ranging modules are adopted in the system to simplify the circuit and reduce the interference from other circuits to ultrasonic range-finding.The error compensation of temperature and humidity is adopted to improve the accuracy.DS18B20 and the humidity sensitive capacitor HS1101 are used in the circuit.The range of the system range-finding is 2~400 cm and the accuracy is 1 cm.LCD12864 is used to display temperature,humidity and surrounding distance.The system has the characteristics of simple structure,reliable working,high accuracy,and real-time distance,temperature and humidity display of obstacles around.It can be mounted in a car for obstacle avoidance,intelligent navigation,and so on. |
