The interest of industry and academia in medical measurements continues to increase, due to technology advancements that allow new sensors, measurement systems, and methodologies, supporting a wide number of medical applications.
The wireless sensor network is becoming a technology of huge interest for a wide variety of applications. Despite the technological developments of smart sensing, issues related to system integration, sensor miniaturization and especially low-power sensors interface circuitry design, still represent major technical challenges. This paper describes the prototype of a smart, low power, wearable system...
Pollution tracking in urban environments can now be performed through a variety of means, both dynamic and stationary. We envision a pollution data acquisition system that can be made accessible to end users by including them in the collection process, not just presenting the results through web pages or applications. We propose a low-cost device, easily configurable by anyone, which measures gas...
Mobile crowdsensing (MCS) is a new paradigm which takes advantage of pervasive mobile devices to collaboratively collect data and analyze physical phenomenon. As mobile devices are owned and controlled by individuals with various capabilities and intentions, a main challenge MCS applications face is to ensure the credibility of the crowd contributed data. Existed works attempt to increase confidence...
To realize indoor environmental sensing, which is a key technology of providing smart services in smart city, with low cost, our research group has proposed a small IoT device named sensor box. In the previous sensor box, however, it is difficult to deploy for the smart city with some problems. In this paper, we propose an indoor environment sensing service using autonomous sensor box to adapt the...
The increasing availability of smartphones equipped with barometric sensors enables their use as barometric altimeters. However, an accurate measurement requires updated information about the temperature and the mean sea level pressure at the location of the measurement. With this aim, this work proposes, analyzes, and compares spatial interpolation methods applied to atmospheric pressure and temperature...
Some of the potential applications of barometric altitude readings (derived from atmospheric pressure measurements) include, but are not limited to, a) floor identification inside large buildings (e.g. museums, shopping malls, etc.), b) fall detection of a human body in the direction of medical monitoring systems and c) determination of an airplane’s position angles. Implementation of these pioneer...
Platinum doped tin oxide (SnO2: Pt) powders were obtained by employing novel methods, which are a mixture of chemical and physical synthesis methods. The powders were prepared from tin chloride and urea as precipitant agent. The resultant SnO2 powders are milled in a planetary ball mill. Finally, a noble metal, platinum (Pt), was added to the milled SnO2 powders via bulk and surface doping methods,...
Clinical techniques for monitoring livestock health are insufficient, as they provide only sporadic information and required too much resource investment in terms of time and veterinary expertise. The animal health monitoring system that is allocating hardware which will mount on the animal body, at present there are no such systems which will provide on current status of the animal. At present to...
In the context of modern agriculture, it is important for farmers and agricultural consultants to count with technological tools that allow an appropriate monitoring of the development of the crop, and of the water and fertilizers applied among other. These objectives can be achieved if information of the soil-water-crop-atmosphere complex system is organized and on-line available for the users. This...
The objective of this work is to develop a ZnO conductometric gas sensor to monitor two key pollutants in indoor environments: benzene and formaldehyde. Conductometric sensors are widely used for this purpose. The final aim of the sensor is to be integrated in an air quality measuring system connected to the HVAC (Heat Ventilation and Air Conditioning) system so that ventilation is activated according...
The identity of a material may be obtained by measuring its emis-sivity spectrum. Unfortunately, hyperspectral remote sensing instruments measure spectral radiance, which is a nonlinear function of the material's emissivity and temperature, the atmospheric downwelling radiance, and other factors. Therefore, accurate interpretation of hy-perspectral data requires estimation and separation of these...
In this paper, the main goal of project FREDE (FREon Decay Experiment) have been presented. is to study the disintegration phenomenon of chlorofluorocarbons (CFC's). As radiatively active gases present in the Troposphere and Stratosphere they influence the depletion of the Earth's ozone layer and the increase in the greenhouse effect. This experiment consisting of test samples reservoir exposed to...
In order to reinforce its contribution to the ocean monitoring, the Spanish Institute of Oceanography (IEO) deployed in June 2007 an oceanic-meteorological buoy (AGL Buoy, 43°50.67' N; 003°46.20' W, and 40 km offshore, www.boyaagl.st.ieo.es/) in the southern Bay of Biscay. The buoy is equipped with a suite of field-proven sensors for the measurement of atmospheric and hydrological parameters at the...
The concept of wireless system of threats monitoring with self-organizing network of multipurpose data transfer nodes are presented. Two practical applications of this system are also presented. The first of these is the Global Wireless Monitoring System for Containers, and the second is the Mobile Monitoring System for Gas Air Pollution Measurements.
Superconducting Submillimeter-Wave Limb-Emission Sounder (SMILES) is a sensor for atmospheric observation at 640 GHz from the International Space Station. Since the launch in Sep. 2009, SMILES has been showing the excellent observation performance. The results of SMILES development are summarized.
A series of small, lightweight, autonomous spectrometer systems has been designed in Tartu Observatory. They are used for obtaining top-of-canopy spectral reflectance measurements for vegetation remote sensing, validation of radiative transfer models, and reflectance-based vicarious calibration of satellite and airborne sensors. The spectrometer systems are based on miniature spectrometer modules...
Fires and explosions are some of the most difficult environments in which to perform sensing. A technology is reviewed that measures the temperature versus time relationship of such rapid thermal events. It utilizes the dependence of luminescence on the trap populations of dispersed micro- and nano-particles. The thermoluminescence (TL) of various oxide microparticles gives direct information on temperature...
