The node hardware of wireless sensor network system is designed and implemented tor environmental monitoring. The μC/OS-Ⅱ embedded real time operation system is transplanted successfully on sink node processor. Combined with the features of the WSN sink node, a multi-task scheduling mechanism is designed. Two different models of real-time data acquisition and on- demand data acquisition are designed. The serial communication program is developed and the real-time monitoring of the WSN settsor nodes is implemented. Test result shows that this system performs well.
