EXTENDED ABSTRACT Soil moisture plays a vital role in the atmosphere-land interactions, hydrological simulation, weather numerical prediction and agricultural arid monitoring. It may control the partition of water and energy into sensible heat flux, latent heat flux, evapotranspiration, runoff and baseflow between land and atmosphere respectively. In order to obtain the profile of soil moisture...

This paper addresses the use of capacitive measurement principles for process instrumentation. A brief review on capacitance-based sensors to measure industrial process parameters is provided. A capacitance-to-digital conversion system developed at the Sensors Group at our Institute is presented. Applications of capacitancebased process instrumentation for moisture sensing, flow velocity determ...

26 It is well documented that capacitance-based soil moisture sensor measurements are particularly influ27 enced by particle size distribution, density, salinity, and temperature of a soil, in addition to its moisture 28 content. Moreover, the equations provided by manufacturers of soil moisture sensors are often only 29 applicable to a limited number of soil types, thus yielding significant er...

This paper aims in providing a user friendly, reliable and automated water pumping system. The paper aims in designing a system which is capable of detecting moisture level in the soil and capable of taking the decision of switching ON/OFF water pump. The system also uses temperature sensor to detect the temperature and automatically the fan speed can be controlled like coolants. In this paper ...

Optofluidic, lab-on-a-chip fluorescence sensors were fabricated using buried anti-resonant reflecting optical waveguides (bARROWs). The bARROWs are impervious to the negative water absorption effects that typically occur in waveguides made using hygroscopic, plasma-enhanced chemical vapor deposition (PECVD) oxides. These sensors were used to detect fluorescent microbeads and had an average sign...

Currently used methods for estimation of moisture content in paper pulp are restricted to levels of moisture concentration under 90%. Some of the existing methods require less practical double-sided contact measurements. A few other methods make restrictive assumptions, such as the constituents of the pulp that determine its conductance. This paper presents a technique that uses fringing field ...

Currently used methods for estimation of moisture content in paper pulp are restricted to levels of moisture concentration under 90%, and also assume that there are no additives in the pulp. This paper presents a technique that uses fringing field interdigital sensors to measure moisture concentration in paper pulp in the presence of calcium carbonate. The method proposed in this paper uses sin...

The potential of Synthetic Aperture Radars (SARs) for measuring soil moisture has been recognised about 30 years ago, but still today the search for suitable sensors and widely applicable soil moisture retrieval algorithms is on-going. Because it is now important to find new directions in SAR soil moisture research, the current state of the art in SAR technology and methodological issues must b...
