一种温湿度采集模块的设计及应用研究

More accurate measurement must be carried out in order to achieve the control of the environmental temperature and humidity. Based on this, this paper design a kind of temperature and humidity acquisition module ,which can display independent on the scene and has the remote communication capabilites by making use of P89LPC922 single-chip microcomputer as well as digital temperature and humidity sensor chip SHT11, introduce the hardware and software designment, communications protocols and some typical methods of work. Experiments show that the module greatly simplifies the software and hardware designment of system and is very suitable for modern environment temperature and humidity monitoring group.
