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.
