摘　　要：主要介绍一种利用PIC单片机定时器将热敏电阻数字化的方法。该系统采用PIC单片机,外围配置几个电阻、电容,即可实现热敏电阻数字化。同时PIC单片机还可接收处理微机的各种命令,使得热敏电阻数字化、智能化。热敏电阻数字化技术已被用于多点温度遥控遥测系统中。该系统原理简单,测量精度较高,与微机通信方便,性能价格比高。It discusses a technique of making thermal sensitive resistance digital by means of PIC timer. The technique uses PIC single chip and puts several resistances and capacitances peripherally so that it can make thermal sensitive digital. At the same time,PIC single chip can accept and process all kinds of orders from a computer,causing thermal sensitive resistance digital and intelligent. A technique of making thermal sensitive resistance digital has been used in temperature remote control system. Using this technique,there are the simple theory,high measure precision,convenient communication with a computer,and the high ratio of performance to price.
