As traditional environmental monitoring system wiring complexity, high power consumption, equipment maintenance inconvenience and other issues, the ZigBee wireless environmental monitoring system with CC2530 chip as the core is designed. The system use CC2530 as the main chip, build wireless networks in order to send and receive data between the coordinator node and field terminal nodes, achieve communication between the coordinator node and PC by serial communication technology. A brief introduction for the system from four aspects:the overall design scheme of the system, the hardware design of the system, the software design of the system and the performance test of the system. The experiment proves that the system is stable, real-time, low power consumption, scalability, and can be widely applied to these occasions where environmental parameters require a relatively high.
