Wireless SensorsLaajuus (5 ECTS)

Objective

Give an understanding of Sensing, Sensors and Sensor Classifications. Give an understanding of the benefits of Wireless Measurements and what their intended application areas are. Give an idea of what their limitations and current status are and future developments. A Wireless Sensor Network is a self-configuring network of small sensor nodes communicating among themselves using radio signals, and deployed in quantity to sense, monitor and understand the physical world. Learning that sensor network is an infrastructure comprised of measuring, computing, and communication elements that gives an administrator the ability to instrument, observe, and react to events and phenomena in a specified environment. The environment can be the physical world, a biological system, an information technology (IT) framework or Industrial Automation system. Network sensor systems are seen by observers as an important technology that will experience major deployment in the next few years for a plethora of applications. There are four basic components in a sensor network: (1) an assembly of distributed or localized sensors; (2) an interconnecting network (3) a central point of information clustering; and (4) a set of computing resources at the central point to handle data correlation, event
trending, status querying, and data storage.
