基于Zigbee的温室无线传感器节点设计与实现

Design of Wireless Sensor Network Nodes of Greenhouse Based on Zigbee

基于Zigbee的无线传感器网络具有广泛的应用前景。为此,基于Zigbee协议设计了一种带扩展板的节点,传感器可根据需要配置,从而提高了系统应用的灵活性。处理器选择超低功耗片上系统CC2430,其集成了8051CPU和无线射频收发器CC2420,所设计硬件系统外围器件少,功耗低。

The wireless sensor network has vast application prospect,This article designs a kind of node with expansion board based on Zigbee protocol.The sensor can be configured according to requirement.This measure improves the flexibility of the system.We select CC2430（system on chip） as the processor,it is integrated with the 8051 processor and the CC2420 RF receiver and transmitter.The hardware system designed has a low power consumption,and has very few peripheral device.
