摘要：体温计是人们日常生活中的必备品，但是传统的水银体温计测量时间长，读数也不方便.本课题基于传统体温计的这些缺点设计出一种新型的电子体温计，它在测温精度能与传统的水银温度计相媲美的情况下，大大的缩短了测温时间，携带方便，对环境几乎没有污染.本次设计以单片机为整个体温计的核心,运用红外线原理去设计一个基于单片机的无线电子体温计，利用热释电红外传感器,采集人体发射出的红外线，再将转换之后的电信号通过 A/D 转换送入单片机,由MCS—51 单片机来实现温度值的转换及送入 LED 显示，同时还加入了时钟功能和超温报警功能,在软件的控制下,实现智能化的体温测量，精确测温，使设计具有有用性。关键字：体温计、红外线、单片机Abstract: Thermometer is an essential goods in our daily life， but the traditional measurement of the mercury needs a long time, reading is not convenient. This subject which based on the traditional thermometer 'defects designed a new type of electronic thermometer， has comparable circumstances on temperature measurement accuracy with traditional mercury thermometers, greatly reduced the temperature time， and it is easy to be carried, it has almost no pollution on the environment . The design use a microcontroller as the core of the thermometer, use infrared principles to design a microcontroller-based wireless electronic thermometer, use pyroelectric infrared sensors， collect the infrared that body emits， then deliver the signal to the microcontroller by A / D conversion, use the MCS-51 microcontroller to implement the conversion ，and deliver the temperature value into the LED display, this design also added a clock function and over—temperature alarm function, under the control of software, intelligent temperature measurements ， accurate temperature measurement， make the design practical。Keyword: thermometer、infrared、microcontroller目 录摘 要IAbstractError: Reference source not found目 录2引言E...
