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.
