基于超声波传感器的测距报警系统设计

Design of System for Distance Measurement and Alarm Based on Ultrasonic Sensor

超声波具有指向性强、传播距离远、检测迅速方便等特点。超声波传感器常用于与距离有关的测控方面,如工业现场的位置监控、液位测量等。本文利用超声波传感器设计了一种测距报警系统并对其测试分析。

ultrasonic is a good method for measurement with its advantages,for example,straight path,far distance,quick measurement,easy caleulatation and so on. Ultrasonic sensor is used to measure and control distance,for distance, mornitoring and controlling position on industry site, measuring height of liquid and so on.This papers is about a system for distance measurement and alarm based on ultrasonic sensor with the experiment result.
