Temperature Measuring and Monitoring System of the Building——Analog-to-Digital Converter Module

论文主要介绍了在单片机的应用系统中,被测量对象的有关变量,如温度、压力、流量、速度等非电物理量,须经传感器转换成连续变化的模拟电信号,这些模拟电信号必须转换成数字量后才能在单片机中用软件进行处理。实现模拟量转换成数字量的器件称为A/D转换器。A/D转化技术在如今科技系统迅猛发达的时代中,起到了中流砥柱的作用。这种技术为现代化社会电子产品的诞生奠定了重要的基础。

This article mainly introduced the related the non-electric physical variable that surveyed to the object, such as the tempera- ture, the pressure, the current capacity, the speed and so on in the application system of single chip mieyoco. These must be converted to the analog electrical signal which changes continuously by the sensor transforms, then transform into the digital variable that can be processed in the single chip micyoeo with the software. The device that can realize the covering from simulation variable into the digital variable is called A/D convertor. The AD conver technology played an important role when it is such a fast-developing time in teehnoledgy. The technology has laid an important foundation for the birth of the modernized society electronic products.
