With the rapid development and improvement of modern information technology, people have higher requirements for their living environment. They hope they live healthily and comfortably. During recent years, especially the quick development of information technology which enables all kinds of wireless communication technology to improve unprecedentedly. So,the thesis utilizes ZigBee technology to exploit and design the wireless home environmental monitoring system. In the system, the sensor node(as well as terminal node) can choose temperature, humidity, brightness etc. Therefore, the wireless network terminal module of the thesis choose the CC2530 chip as the platform for realizing receiving and sending of the information data. The chip has a single chip with 8051 core and has certain memory space. Thus, it can realize its function by adding a little peripheral circuit without extra single chip. The received data processing in the data receiving terminal(that is coordinator node) send to PC for people’s real-time monitoring. The thesis designed the display interface in PC for people’s operation and data monitoring conveniently. The system works reliably which can obtain correct environmental data and realize real time monitoring. Keywords： ZigBee;Wireless sensor networks; environmental
