【正文】 wo nodes(the main chip of development board designed as CC2530 chip)， one is coordinator， and another is enddevice． The coordinator is responsible for creating the work and maintaining the work． The Enddevice is responsible for keeping the various functional modules work well， and passing the data to the coordinator node． The main function modules of the hardware design involves temperature and humidity module， smoke detection module， relay module and human infrared sensor module． This article studies the security system of home working from the theory and principle aspects， and the hardware design of a simple home’s environment safety monitoring system has been designed． 【 Key words】 System of Smart Home Inter of Things Smart House Security sensor work 重慶郵電大學本科 畢業(yè)設計（論文） IV 目
