Design and Implementation of Nodes Based on CC2430 for the Agricultural Information Wireless Monitoring

I A newly developed sensor node, which can monitor soil temperature, is designed through modular design method. The hardware of sensor node is base on a CC2430 micro-controller and DS18B20 temperature sensor. The software system includes the temperature collection, information transmission, and the communication between two nodes. The node can collect soil temperature information and then send it to upper network node. The designed node possesses compact structure, stable performance, and small volume. The effective communications distance between nodes reaches 80 m and the error ratio is approximately 1%, which meets the requirement of agricultural information collection. This study provide better hardware platform for further researching the communication protocols of wireless sensor networks.
