EBOOK - Electronic Portable Instruments - Design and Applications (Halit Eren)

Today, in broad terms, portable electronic devices are very common. They are used in a large range of applications: science, engineering, research, and industry. They are not confined to only these areas, but find many applications and use by ordinary people in their everyday lives.
In fact, these portable devices constitute a large part of consumer electronics, including portable tapes, radios, CD players, TVs, VCRs, cameras, power tools, calculators, games, toys, cellular telephones, clocks, watches, pacemakers, thermometers, microphones, shavers, notebooks, palm computers, electronic diaries, etc. Hence, the list can go on and on.
An important section of portable electronic devices is the electronic portable instruments that are used for measuring and monitoring purposes.
Particularly in recent years, due to progress in the electronics technology, many instruments conventionally known as bench-top instruments are being replaced by their portable counterparts. As the electronic components get smaller in the form of microelectronics, the physical dimensions of conventional instruments become smaller too.

Therefore, miniaturization of many features of the larger and bulkier electronic instruments opens up new avenues of applications in many areas. They find applications that include laboratory instruments, medicine, environmental monitoring, space explorations, optics, chemistry, biology, petroleum industry, aerospace, manufacturing, pollution control, military devices, navigation, personal security,
hobby devices, process control, and so forth. The applications of portable instruments do not end in the areas mentioned above, but are found almost everywhere. They are used to measure variables such as size, light, color, temperature, pressure, radioactivity, currents, voltages, bacterial and viral presence, water and other chemical analyses, latitude, displacements, changes in position, chemical composition of solids, liquids, and gases, sound analysis, breath analysis, human or machine orientation, acceleration, homogeneity, humidity, quantity, density, etc.
