低成本高精度小型智能测温仪设计与实现

Design and Implementation of a Small Intelligent Thermometer with Low-Cost and High-Precision

基于模块化设计思想,采用Atmega16单片机,实现了高精度测量、高可靠性、低功耗的小型智能测温仪的设计.该系统运用软件编程的方法,将Atmega16单片机自带的10位A/D转换器分辨精度提高到了11位,使系统的输出显示精度提高了一倍.该系统能方便的与计算机终端相连,从而能建立大型的温度监测系统.

This system is based on the idea of modular design, which has achieved a high precision measurement,high reliability and low power consumption of small thermometer intelligent design by Atmegal6 microcontroller. The system craftly uses software programming method. The 10-bit A/D converter carried by Atmegal6 microcontrolle is improved to resolution accuracy of 11-bit, which makes the accuracy of the output doubled. The system can be conveniently connected with computer terminals so that it could build large-scale temperature monitoring system.
