基于 51 单片机的智能温度传感器摘 要 智能设备,众所周知,是我们现代 21 世纪的新的一项发明,那么以后的发展方向,也必然是智能。智能可以按照我们人类的欲望并且按照我们想让他工作的方式服务人类,那么我要做的智能温度报警系统就为这其中一项不可或缺的体现,这次设计的智能温度报警系统,根据我个人观察查阅资料下来,这种温度报警系统是高低温智能的,通过温度传感器 Ds18B20 来测试温度,传感器的检测原理简单,就是温度高了会报警,温度低了同样也会报警。检测到的温度一般都是几十点几度这样,这种传感器精确度为零点一摄氏度。并具备 rom 功能,掉电之后他的数据还能保存的很好,如此一来我们没断电之前的数据就可以保存好。另外 ,1602 液晶屏,这个液晶屏会把我们的工作状态实时显示在上面,这次设计的使用的电源不是电池装的,而是使用 USB 线供电。关键词:STC89C52 单片机 DS18B20 1602 液晶模块IIntelligent temperature sensor based on 51 single chip microcomputerAbstractIntelligent device, as we all know, is a new invention in our modern 21st century, so the future development direction is also bound to be intelligent. Intelligent can according to our people's desires and serve mankind according to the way we want him to work, so I want to make a smart temperature alarm system is one of the indispensable reflected, the design of intelligent temperature alarm system, according to my personal observation data access, the temperature is high and low temperature intelligent alarm system, test temperature by temperature sensor Ds18B20, sensor detection principle is simple, is the high temperature will call the police, the low temperature will also report to the police. The temperature is usually a few tens of degrees or so, and this sensor is accurate to 0.1 degrees Celsius. And with ROM function, his data can be saved very well after the power, so that we can save the data before the power. In addition, 1602 LCD screen, this LCD ...
