Composite sensitive functions - observation of natural phenomena surrounding the sensor, the signal common sound, light, electricity, heat, power, chemical and other. Sensor measurements are generally in two ways: direct and indirect measurements. The intelligent sensors with complex function that can simultaneously measure a variety of physical and chemical quantity sensor which gives substance can be more fully reflect the movement of information. Photosensor is one of the most common sensor, its wide variety, are: photocell, photomultiplier, photoresistor, phototransistor, solar cells, infrared sensors, ultraviolet sensors, fiber optic photoelectric sensors, color sensors, CCD and CMOS image sensor. It is sensitive to wavelengths in the visible wavelength nearby, including infrared and ultraviolet wavelengths. Light sensor is not limited to the detection of light, it can be used as the sensing element composed of other sensors, for many non-power sensor for detecting tension, as long as these non-electricity is converted to an optical signal can change. Optical sensor is one of most productive, the most widely used sensors, which occupies a very important position in the automatic control and non-power electrical measurement technology lead in. The simplest light sensors [2] is photosensitive resistance, junction when photons impact will generate electricity. Sensor resistance strain gauge metal with a strain effect, ie a mechanical deformation under external force, so that the resistance value of the consequent change accordingly. Resistance strain gauges are mainly two types of metals and semiconductors, metal strain gauge type metal wire, foil, film style points. Semiconductor strain gauge with high sensitivity (usually silk style, foil a few times), transverse effect is small.
