ABSTRACT

Sensors perform a significant part of an electronic device by providing the interface

to the surrounding range of interest. The sensors may be of wireless or data-bus

connection, and can consist of a huge number of miniaturised micro-technology-

based solutions or state-of-the-art design that intend to deliver data in effective,

consistent or intelligent applications. Most applications of today still use single

sensor (or mostly a very few) in applications intended to measure quantifiable

values in a restricted partially defined range of the environment. This structure

may instead result in a physical property were the sensor will contribute to the

specific part of the object and change its quantitative parameter(s) caused by the

measurement system. For example, measuring the temperature in a sealed cup of

water will probably affect the measurement if a sensor is entered into the water,

due to the difference in temperatures between the sensor unit and the measured

object, i.e., the water.
