The cross-platform transmission system for analog WSN based on Arduino is different data model generated by Arduino controller. And it sends these data to service agent via ZigBee wireless transmission, then transfers to specified server for storage. The network test platform will read the stored data in server and display in real time. Also the network test platform can achieve remote control by sending instructions. All the experiments and data transmission analyses indicated that the system has strong-time capability, high precision and easy handling. And the system can be widely used in security, medical treatment, and industrial automation and so on.
