课程设计基于单片机温湿度传感器.doc

...摘要由于温度与湿度不管是从物理量本身还是在实际人们的生活中都有着密切的关系,所以温湿度一体的传感器就会相应产生。DHT11与单片机之间能采用简单的单总线进行通信,仅仅需要一个I/O口。操作简单,使用基亚5110二手屏幕显示DHT11传感器读出来的温度和湿度值。关键字:AT89S52;5110液晶;DHT11传感器;单总线AbstractBecauseofthetemperatureandthehumidityfromboththephysicalquantityitselforintheactuallifeofpeoplearecloselyrelated,,onlyneedaI\/,:AT89S52;DHT115110LCD;sensor;singlebus...目录引言---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------‘0’信号表示方法-----------------------------‘1’信号表示方法-----------------------------42、诺基亚5110液晶简介(PCD8544驱动)-----------------------------------------------------------------------:---------------------------------------------(AC)---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------63、总结-------------------------------------------------74、谢辞-------------------------------------------------85、参考文献---------------------------------------------96、附录-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
