The accurate reading of a customer water-meter is important as it is the main revenue base for the water authorities. The traditional data collection process is still common in developing countries despite the inherent inefficiency, inaccuracy and labour intensity. A solution to improvement could be based on sensor and communication technology. In this research an automatic water meter reading ...

Electronic-nose devices have received considerable attention in the field of sensor technology during the past twenty years, largely due to the discovery of numerous applications derived from research in diverse fields of applied sciences. Recent applications of electronic nose technologies have come through advances in sensor design, material improvements, software innovations and progress in ...

The ongoing vivid advance in integration technologies is giving leverage both to computing systems as well sensors and sensor systems. Both conventional innovative systems, e.g., following bio-inspiration from nervous or neural networks, require efficient interfacing an increasing diversity of under the constraints metrology. realization sufficiently accurate, robust, flexible analog front-ends...

This work presents and evaluates different approaches of integrated optical sensors based on photonic circuit (PIC) technologies for refractive index sensing. Bottlenecks in the fabrication flow towards an applicable system are discussed that hinder a cost-effective mass-production disposable sensor chips. As device, waveguide coupled micro-ring approach is chosen which manufactured 8” wafer le...

Hydromagnetic flow and mass transfer of a viscous incompressible fluid over a microcantilever sensor surface are studied in the presence of slip flow. In addition, chemical reaction at the sensor surface is taken into account. The governing equations for the flow are reduced to a local nonsimilarity form. Resulting equations are solved numerically for various values of flow parameters. Effects ...

In this paper, we show anew image sensor for measuring traffic flow. The image sensor is set at an intersection. The image sensor measures t r af f i c flow by vehicle tracking. The tracking is done by gray level pattern matching. Gray level pattern matching is suitable for outdoor use since it is robust against change of scene brightness. Then we provide the hardware for high speed gray level ...
