“…For every crop, its soil moisture and temperature requirement is different in depths and growing periods. The soil moisture and temperature monitoring devices existed only can obtain the information in one soil layer [6][7][8][9][10], which can't meet the need of modern and efficient agriculture.…”

The temperature and moisture of single soil layer is difficult to represent the real growth environment around crop root. The measurement of temperature and moisture in multilayer and multipoint soil is easy to know water demand around crop root during its growth period deeply and accurately. It also can improve the water utilization coefficient and achieve basic data for the research on soil water infiltration variation and intelligent precise irrigation. In this paper, a monitoring system for multilayer soil temperature and moisture was designed based on WSN using the core ship CC2530. The system consists of three parts: monitoring nodes, a gateway node and a system platform in upper computer. The monitoring system was deployed in farmland. A lot of soil temperature and moisture data was got in real-time, and the changes of soil temperature and moisture in four soil layers with depths of 10cm, 20cm, 30cm and 40cm were obtained. The application in the farmland shows that the system is practical, functional and stable.

I would like to thank my committee members for serving on my committee. I would like to thank all of my colleagues at IIHR for their input, especially Dr. Jim Niemeier for helping me to understand the architecture of the soil moisture network that was previously deployed in Ames, Hamid Fahim Rezaei for discussing various communications topics that helped me to come up with new ideas, and Nick Sitter for his help with the parasitic power circuit, the build of the first hardware prototype, and advice on using the ATTiny45 chip. I would also like to thank IIHR for their financial support during the time that I was working on this project. Finally, I would like to thank my advisor, Dr. Anton Kruger, for his support. This development would not have happened if it were not for his ideas and our many long discussions about the fundamental issues of implementing this type of network. v TABLE OF CONTENTS LIST OF TABLES.

“…Recently, IFC has been developing the next generation rain gauge sites, which incorporate both soil moisture and soil temperature sensors. These sites, described in [5], will be deployed across the state and will provide researchers at The University of Iowa with the real-time data necessary to provide flood forecasts to local communities.…”
