Abstract 
With the rapid development of Internet of Things technology, wireless sensor networks are increasingly widely used in various fields. Among them, the wireless sensor network based on ZigBee technology shows great application potential in smart home, industrial automation, environmental monitoring and other fields with its low power consumption, high reliability, self-organization and other characteristics. This paper aims to discuss the design principle, key technologies and application scenarios of wireless sensor networks based on ZigBee technology, in order to provide references for the in-depth research and application of this technology. When designing a wireless sensor network based on ZigBee technology, it is first necessary to consider the application scenarios and requirements, and clarify the number of sensor nodes, network topology, communication distance and power consumption requirements. Select the right sensor hardware and ZigBee modules according to your needs, you can buy the development kit on the market, or you can design your own hardware according to your needs. Next, the location and layout of nodes are determined to optimize communication quality and network stability. When choosing network topology, we can consider star, tree, network and other structures, and use network simulation software to simulate and optimize. In terms of key technologies, the ZigBee protocol stack is the core of wireless sensor network implementation. It provides communication protocols and data transmission standards between devices, ensuring proper communication between nodes. In addition, in order to ensure the accuracy and reliability of the data, it is also necessary to use data fusion, data compression and other technologies to process the collected data. In terms of software development, appropriate programming languages such as C and Python can be selected to develop and code using the ZigBee protocol stack. Wireless sensor networks based on ZigBee technology are widely used in many fields. In the field of smart home, the sensor node senses the temperature, humidity, light and other information of the home environment to achieve intelligent control and management. In the field of industrial automation, the temperature, humidity, pressure and other parameters on the production line can be monitored in real time to improve production efficiency and quality. In the field of environmental monitoring, sensor nodes are used to collect environmental temperature, humidity, air quality and other information to provide decision support for environmental protection departments. Wireless sensor networks based on ZigBee technology have wide application prospects and huge market potential. By continuously optimizing the design and application scheme, it can further expand its application scope in the field of Internet of Things, and bring more convenience and benefits to people's production and life.
