    摘要:

    設(shè)計了一種能夠監(jiān)測土壤溫度的無線智能傳感器節(jié)點,，硬件系統(tǒng)基于片上系統(tǒng)CC2430和DS18B20進行開發(fā),，軟件部分包括溫度采集和數(shù)據(jù)傳輸,。實驗表明,，該節(jié)點可以實現(xiàn)土壤溫度信息的采集和傳輸，且結(jié)構(gòu)緊湊,、工作穩(wěn)定和功耗低,。節(jié)點之間有效通信距離可達80m，誤碼率為1%左右,?？梢詽M足精細農(nóng)業(yè)作業(yè)要求,，同時也為無線傳感器網(wǎng)絡(luò)通信協(xié)議的進一步研究提供了實驗平臺,。

    Abstract:

    A new smart sensor node to monitor soil temperature, including hardware and software, is developed through modular method. The hardware system is developed based on a CC2430 micro-controller and DS18B20. The software system includes the temperature collection and information transmission. The results show that the node can collect soil temperature data and then send the data to the upper network node. This node possesses compact structure, stable performance and low energy consumption. The effective communications distance among nodes reaches 80m and the error ratio is approximately 1%, which meets the requirement of precision agriculture. The node provides a better hardware platform for further study on the communication protocols of wireless sensor networks.
