Design of an Experiment for Data Acquisition Based on Wireless Sensor Network

Wireless sensor network is the core technology of the national Internet of Things,and is one of the important developing directions of information science.In this paper,a comprehensive experiment for spatial data acquisition was designed and implemented for the course of "Sensor Network and System" in the School of Electronics and Information in Tongji University for undergraduates,based on a new generation wireless sensor node with the support of the open source OpenWSN software.The wireless sensor node adopts the high-performance and low-power Cortex-M3 based STM32 microcontroller and the high-sensitivity wireless transceiver cc2520.This experiment enables students to fully understand the advantages,disadvantages and technical challenges of wireless sensor network.
