数字温度计
引言
随着时代的进步和发展,单片机技术已经普及到我们生活,工作,科研,各个领域,已经成为一种比较成熟的技术,本文将介绍一种基于单片机控制的数字温度计,本温度计属于多功能温度计,可以设置上下报警温度,当温度不在设置范围内时,可以报警。
人们生活水平的不断提高,单片机控制无疑是人们追求的目标之一,它所给人带来的方便也是不可否定的,其中数字温度计就是一个典型的例子,但人们对它的要求越来越高,要为现代人工作、科研、生活、提供更好的更方便的设施就需要从数单片机技术入手,一切向着数字化控制,智能化控制方向发展。
本设计所介绍的数字温度计与传统的温度计相比,具有读数方便,测温范围广,测温准确,其输出温度采用数字显示,主要用于对测温比较准确的场所,或科研实验室使用,该设计控制器使用单片机STC89C51,测温传感器使用DS18B20,用3位共阳极LED数码管以串口传送数据
