Design of transceiver module of wireless sensor network nodes

摘要

The wireless sensor network (WSN) is defined as a networks, which is setup by some sensor nodes of self-organizing. In this paper, 315 transceiver module of wireless sensor nodes is designed based on the main control chip AT89C51. In the system, the MAC protocol for communication and working software are also set up. To sense the environment temperature, DS18B20 is used to form the basic sensor nodes. Finally, the experiment results for testing the function of the nodes show the correctness and the affectivity of the proposed design.
