Clark electrode is a well-known sensor for measuring concentration of dissolved oxygen in a water solution. This type of electrochemical sensor has an advantage of enabling detection of very low oxygen concentration. Although Clark electrode is typically used for measurement of dissolved oxygen, our research showed that the same electrodes can be successfully applied for measurement of other dissolved gases. We investigated a possibility of applying the same principle to dissolved hydrogen concentration measurement, and also the possibility of simultaneous measurement of both dissolved oxygen and hydrogen concentrations in the same water solution. We adapted Clark electrode sensor to measure dissolved hydrogen by choosing the appropriate polarization voltage level. We studied the influences on dissolved hydrogen measurement, such as choice of polarization voltage, temperature, salinity, and solution pH. We investigated the polarization voltage influence on sensor sensitivity and observed hysteresis in sensitivity that occurs with cyclic increase and decrease of polarization voltage. We proposed and described measurement setup that was used for experimental verification of proposed measurement method and sensor characteristics. The measurement results of sensor characteristics are presented, regarding the influences of polarization voltage, temperature dependence, salinity (fresh water and 380/00 NaCl solution) and pH value (6, 7, 8).

We present an autonomous-mobile gas detection system to assess the measurement of specific gas concentrations in a wide range of outdoor applications. This is especially of interest in those harsh environments where it is impractical or uneconomical to install a fixed array of gas sensors. The system is able to work in potentially hazardous emissions areas - toxic gas leakages - in completely secure working conditions for the operators. Used as payload on a Unmanned Aerial Vehicle (UAV), it can provide gas measurements with adaptive and high resolution sampling rates in accordance to gas concentration and carrier speed. Each measurement is associated with the location provided by the embedded GPS module. Remarkable features are the small size, the low power consumption and costs, compared to traditional systems. Finally, we presents a novel approach to optimize the speed of the vehicle and the system power consumption based on gas sampling frequency, which allows lifetime maximization and leakage detection reliability.

This paper describes how to use sensor information in international disaster management operations. The focus is on enabling sensor interoperability by using standardized interfaces. For this work the Open Geospatial Consortium (OGC) Sensor Observation Service (SOS) is used to exchange sensor information between different systems. Further individual sensor values have to be interpreted to bring benefit to commanders in disaster operations. We are proposing a Sensor Fusion Engine to combine sensor data stemming from heterogeneous sources and provide a condensed output in different standard formats and protocols. An example of such a format is the Common Alerting Protocol (CAP) which is a standardized interface used in disaster operations. Real world deployments in large scale disaster exercises have shown the applicability of the approach.

The tragic Deepwater Horizon accident in the Gulf of Mexico in 2010 as well as increase in deepwater offshore activity have increased public interest in counter-measures available for sub-surface releases of hydrocarbons. Available remote-sensing techniques are efficient and well developed for surface disasters but they are not useful underwater. Along these lines, this paper analyzes application of Autonomous Underwater Vehicles (AUV) with integrated submersible fluorometer for underwater detection of hydrocarbons. Experiments with rhodamine, which was used as a replacement for oil, showed that the proposed system can be efficiently used both as an input into numerical model and consequent visualization of spatial distribution of pollutant.

Advances in animal tracking technology allow for improvement in farm resource management, animal welfare and the possibility of an overall reduction in running costs. We describe a light-weight solar-powered position sensor tag for livestock and a corresponding base station. The livestock ear tag weighs less than 40g and utilises 868MHz SRD/ISM frequency band for telemetry. This provides configurable wireless connection for data retrieval triggered by a base station, reducing the overall power consumption of the tags. Data transmission range is 2.4km line of sight and 1km typical. Static testing of the position sensor yields a circular error probable of 6 ±2 metres.

Despite the increasing adoption of smart meters, especially for electrical power measurements, a very large number of utility inspectors manually execute readings of legacy analog meters (e.g., for gas or water utilities). Unfortunately, manual data collection generates a lot of paperworks and is clearly error prone. In this work, authors suggest the adoption of smartglasses to automatize this process. In particular, the embedded camera is used for barcode scanning (in order to identify the user) and for recognizing the meter dial values. The availability of an Internet connection finally allows for exploiting cloud-based repository solutions. In that way data can be easily accessed from both utility employees and customers using simple web services. A preliminary prototype based on the Vuzix M100 device has been realized. Some tests have been carried out, confirming the feasibility of the proposed approach.

The paper presents a novel model-based algorithm for classifying buried metallic targets using spatial and temporal response properties of a pulse induction metal detector mounted on a mobile robot for autonomous landmine detection. In the proposed approach, we firstly derive a simplified analytical model for spatial distribution of the primary magnetic field that corresponds to transmitter/receiver coil geometry of a given metal detector. The sensing head model is then coupled to a metallic target analytical dipole model whose parameters are the magnetic polarizability tensor and the target location. Finally, the forward sensor/target model is fitted to sensor data obtained by spatially mapping the suspected target area using a mobile robot. Inverted magnetic polarizability tensors corresponding to sensor data acquired at different time instances (gates) are used for target characterization and classification. The algorithm is experimentally evaluated on a dataset collected from a test site containing surrogate mines (metallic spheres) and clutter targets.

Wireless Sensor Networks (WSNs) are at the verge of a broad acceptance in demanding industrial applications. Nodes must fulfill key requirements like reliability and deterministic communication, but also energy autarky in order to allow maintenance-free systems. In this paper a system combining low power, robust communication with appropriate methods for energy harvesting and energy management is suggested. By comparing two alternative variants for power-management, constraints of a solar-cell powered node design are derived. The resulting system demonstrates energy sufficiency at standard industrial indoor lighting conditions of 1300 lx for sensor nodes sampling temperature values at 10 Hz and transmitting once per second.

The characteristic bio-impedance spectra of a biological sample can provide important information about its cellular structure, and further, infer useful information about the physical and chemical condition of the sample. In this paper, we present the background detail of a magnetic induction spectroscopy system for non-contact bio-impedance measurements, and some results using this system to obtain the relative permittivity spectra of a range of fruit and vegetable samples, over a frequency range from 160 kHz to 2.5 MHz. Relative permittivity is found to decrease with respect to frequency for each sample tested. This shows clear evidence of dispersion occurring within the samples across the investigated bandwidth.

Advancements in sensor and metering technologies enable us to affordably collect more data than ever before and this data can be used to revolutionize the power industry. The ability to sense and monitor power characteristics in near real time and feed this information to control systems operating to optimize the grid enables better operation of both large and small scale power systems. Real-time power sensors working with a near real-time control system is necessary for a microgrid which has intermittent renewable generation and time varying loads. Knowing how much energy is flowing through the system is crucial for stable operation while islanded and is important to maintain economic feasibility. The application of advancements in cloud communications and embedded sensors can be used to augment the control of a residential microgrid through the real time data collection and control of both loads and generation resources. Using an advanced sub-metering system to monitor the flow of energy through the microgrid, a connection to the ISO's energy market, and local environmental data provides efficient operation and insight into the near real-time operation of the system. The data can also be logged for future analysis external to the system to allow for better future development of control strategies and can be used to make better predictions of energy needs and costs. These predictions can be used to ensure the renewable energy is used in the most economic manner ensuring the best possible equivalent price of energy. Such an integrated and predictive system can also store thermal energy inaugurating a paradigm shift from a “demand response market” to one that becomes an “availability responsive market”.
