这个是基于单片机的温度测量的程序.这个可以测量外界的温度(除芯片的自身的温度外),并且可以手动设置温度的最高和最低值.如果温度低于最低或高于最高值，LED灯就会亮,如果是低于最低温度2度或最高温度2度,蜂鸣器就会响,报警-This is based on single-chip temperature measurement procedure. This can measure the temperature of the outside world (in addition to its own chip temperature outside), and can be manually set the temperature of the highest and lowest values. If the temperature falls below the minimum or higher than the highest value , LED lights will be bright, if it is below the minimum temperature of 2 degrees or the maximum temperature of 2 degrees, buzzer will sound alarm
