The Design of Embedded Wireless Sensor Network Node

Wireless sensor network node as the most important member of the whole network, has some specious characteristics such as small size, low-power consumption, limited capacity of storage and communication and so on, the node design is essential. This paper proposes a wireless sensor network nodes design scheme based on 51 core MPU and the CC2420 RF transceiver chip，introduces the design process of the node's hardware and software. Through the expansion and secondary development of applications, Users can easily build the required application system.
