In recent years, the significance of water protection and conservation is still increasing. Information about the state of water in soil is a key component in soil water monitoring, irrigation control systems and its optimization. The purpose of this work is to create a wireless sensor network for the measurement of soil water potential. The work includes the description of measurement methods, selection of appropriate method and its calibration. It also contains hardware and firmware realization of the two types of wireless modules, the end station with sensors and the base station for data reception. The realized application contains a user program which allows data logging, displays actual data or past characteristics and changes the system settings with a possibility to request system for the necessary information.

Agriculture requires technical solutions for increasing production while lessening environmental impact by reducing the application of agro-chemicals and increasing the use of environmentally friendly management practices. A benefit of this is the reduction of production costs. Sensor technologies produce tools to achieve the abovementioned goals. The explosive technological advances and developments in recent years have enormously facilitated the attainment of these objectives, removing many barriers for their implementation, including the reservations expressed by farmers. Precision agriculture and ‘smart farming’ are emerging areas where sensor-based technologies play an important role. Farmers, researchers, and technical manufacturers are joining their efforts to find efficient solutions, improvements in production, and reductions in costs. This book brings together recent research and developments concerning novel sensors and their applications in agriculture. Sensors in agriculture are based on the requirements of farmers, according to the farming operations that need to be addressed.

The advances in low-power electronic devices integrated with wireless communication capabilities are one of recent areas of research in the field of Wireless Sensor Networks (WSNs). One of the major challenges in WSNs is uniform and least energy dissipation while increasing the lifetime of the network. This is the first book that introduces the energy efficient wireless sensor network techniques and protocols. The text covers the theoretical as well as the practical requirements to conduct and trigger new experiments and project ideas. The advanced techniques will help in industrial problem solving for energy-hungry wireless sensor network applications.

Environmental monitoring in real-time has been more important in automation system nowadays. With the implementation of wireless sensor network, much information about the environment such as temperature, sound, soil moisture level and pressure can be monitored immediately. Especially for soil moisture level, many of the current sensors require the use of a data logger that does not allow the sensors to react to changes of the environment at the same time when the information are being extracted. Data loggers also require cabling which can cause more installation cost and maintenance difficulties. Furthermore, some of the data loggers are not designed for distant monitoring and require the information to be obtained manually resulting in a waste of manpower. Many researches and investigations have been done in the past for the wireless network design. This includes the basic network architecture, structure, the protocols and algorithms used for the wireless network in order to improve the performance of wireless communication. The most important factor to be considered in the designing and implementation of a wireless sensor network is the development of a precise, stable and energy efficient network. This thesis attempts to provide a solution for a convenient and efficient soil moisture network that has previously relied on the data logger in obtaining the information. The sensor network is designed and developed based on the Texas Instrument technology. The architecture is defined by IEEE 802.15.4 standard and the communication protocol between the coordinator and the sensor nodes are also clarified. The soil moisture sensor that is to be improved has been studied with the background of the sensor stated. This leads to the elimination of data logger and the integration of the sensor node to the pre-examined wireless network. Problems regarding the efficiency and cost of the network arise and motivate to the designing and implementation of a new sensor node. The overall system is then reviewed with the steps for the calibration and conversion of the sensor output into volumetric water content. A brief introduction to the use of relay channel is also discussed in the aim to reduce power consumption and increases channel capacity. The investigation of the channel capacity theory for cooperative communication system and the derivation for the formulae are also presented.

This state-of-the-art book clearly explains the basic principles of soil hydrology and the current knowledge in this field. It particularly highlights the estimation and application of measurements and evaluation of soil-hydrophysical characteristics using simulation models, with a focus on elucidating the basic hydrophysical characteristics of soil, such as soil water potential and hydraulic conductivity, as well as the methods of measurement. It also addresses topics such as stony soil, water repellent soils, and water movement modeling in those media. The book presents soil hydrology in a simple way, while quantitatively expressing the soil water state and movement. It clearly and precisely describes basic terms of soil hydrology with a minimum of mathematics. It also includes the latest research findings in the field as well as the basics of the mathematical modeling of water movement in the soil-plant-atmosphere system (SPAS), using original research results to illustrate these issues. This book is of interest to all scientists and professionals in soil hydrology, including beginners, as well as those interested and working in hydrology in general and soil hydrology in particular. In addition, it can also be used by specialists and students in related fields like agronomy, forestry, meteorology, hydrology, environmental engineering, environmental protection, and geography.
