Design and Implementation of Sensor Node for Environment Monitoring Internet of Things
环境监测物联网传感器节点设计与实现

Aiming at the properties that the energy of sensor node in wireless sensor network is generally provided by battery and not easy complementing, a low energy consumption node which is suitable for realtime monitor of environ- ment Internet of things was designed. hhe nodes can be divided to sensor node and sink node. MSP430F1611 is used as the MCU and CC2420 as RFIC in the sensor node. S3C2410 is used as the MCU and CC2420 is used as RFIC in the sink node. The hardware structure and software flow was given. Finally, the data mining accuracy, energy consumption and drop data packet ratio of node were simulated and analyzed. The result shows the sensor designed can satisfy the de- mand of Internet of things, and has the advantage of high accuracy for data mining, low energy consumption and high re- liability.
