The invention of new fluorescence-based chemical sensor has facilitated the myriad potential applications such as monitoring oxygen, inorganic gases, volatile organic compounds, biochemical compounds etc, as the technology is versatile, compact and inexpensive in nature. Depending upon the vital criteriaâ„¢s of accuracy, precision, cost and the ability to meet the environmental range of the intended application, proper sensor can be chosen for the military control based subsystem. Sensor web and video sensor technology are two widely applied sensor techniques, in which Sensor Web is a type of sensor network or geographic information system (GIS) well suited for environmental monitoring and control, where as video sensor technology is used for digital image analysis. In sensor web technology, we have a wirelessly connected shapeless network of unevenly distributed sensor platform or pods, which is very much different from the TCP/IP-like network with respect to its synchronous and router-free nature.

Because of this unique architecture every pod in the network knows what is happening with every other pod throughout the Sensor Web at each measurement cycle. The main requirements for a video sensor technology is an application software and a computer that acts as the carrier platform, which is usually equipped with a Linux or Microsoft operating system upon which the application software works. By programming the digital algorithms the interpretation of digital images and frame rates can be carried out. The video sensor is very much helpful in evaluating the scenes und sequences within an image section of a (CCD) camera.

NEW SENSOR TECHNOLOGY
ABSTRACT
Scientists have developed and demonstrated a fluorescence-based chemical sensor that is more compacting, versatile and less expensive than existing technology of its kind. The new sensor holds promise for myriad potential applications, such as monitoring oxygen, inorganic gases, volatile organic compounds, biochemical compounds. Selecting the right sensors is critical to implementing any military control-based subsystem in which the key factors are accuracy, precision, the ability to meet the environmental range of the intended application and cost.Mainly used two techniques are sensor web and video sensor technology. The Sensor Web is a type of sensor network or geographic information system (GIS) that is especially well suited for environmental monitoring and control.An amorphous network of spatially distributed sensor platforms (pods) that wirelessly communicate with each other. This amorphous architecture is unique since it is both synchronous and router-free, making it distinct from the more typical TCP/IP-like network schemes. The architecture allows every pod to know what is going on with every other pod throughout the Sensor Web at each measurement cycle. The word video sensor (also video-sensor or videosensors) describes a technique of digital image analysis. A video sensor is an application software, which supports the interpretation of digital images and frame rates. Video sensors emerge by programming digital algorithms. The carrier platform of a video sensor is a computer, which in turn is usually equipped with a Linux or Microsoft operating system. Video sensors are being installed on top of one of the mentioned operating systems. And in combination with the carrier platform, it represents a video sensor system. Video sensors are being used to evaluate scenes und sequences within an image section of a (CCD)camera.
