采用51单片机，开发工具为KEIL.主要功能是实现一个多功能温度计。采用1602液晶显示和配合上位机软件共同完成环境温度的检测与报警功能。系统可以通过按键或者上位机修改报警温度上下限。并将数值保存在外置的EEPROM中，以便开机的时候自动加载。-This work is entirely in accordance with the commercial and practical design requirements to enhance the operation of the system easy and reliable use of the basic functions of the works under the premise of focus. In simple terms, the work using a variety of man-machine interactive mode, the user either through the onboard LCD screen or a computer in real time observed in the current environment, temperature, alarm temperature upper and lower threshold and alarm, you can also board push buttons, remote control or computer in real time to modify the alarm temperature upper and lower threshold, and the number of alarm cleared the operation. In terms of reliability, works with a precision thermistor, can guarantee that the measured data more close to the real temperature. The same time, the work can also fully consider the use of works in the real problems may occur, such as the system is powered down. To this end, the works specifically added an EEPROM to save useful data, so that even
