Design and implementation of Zigbee based wireless sensor network for remote SpO2 monitor
Yan Jun Zhou, Zhu Jiaxing · 2010
A wireless sensor network which consists of SpO2 sensor devices, a router, and Personal Area Network (PAN) coordinators was proposed in this paper. These devices of the network are all developed on ZigBee module which consists of a MCU (MSP430F1611) and a ZigBee chip (CC2320). The sensor devices measure the SpO2 data from patients and transmit it to the router. The router schedule a sending time for each associated device and use hierarchical routing to forward data to a specific device. The PAN coordinator extracts the received packages and passes them to the personal computer. A Web-based management method is used to manage the physiological signals which can be displayed on the Web page. The system can collect sensitive health information remotely and has a good applied prospect in remote healthy hare field.
