Wherein, photoconductive cell claims fiber optic tube again, and manufacturing materials commonly used is a cadmium sulfide, also has materials such as selenium, aluminium sulfide, lead sulphide and bismuth sulfide in addition.These manufacturing materials have in the illumination of specific wavelength penetrates down the characteristic that its resistance reduces rapidly.This is because the current carrier that illumination produces all participates in conduction, does drift motion under the effect of extra electric field, and electronics marches on towards the positive pole of power supply, and the hole marches on towards the negative pole of power supply, thereby the resistance of photo resistor is descended rapidly.Photo resistor is to utilize a kind of resistance value that semi-conductive photoconductive effect makes with the resistor that the power of incident light changes, and is called photoconductive detector again; Incident intensity, resistance reduces, and a little less than the incident light, resistance increases.Photo resistor generally is used for the measurement of light, the control and the opto-electronic conversion (variation of light being converted to the variation of electricity) of light.Photo resistor cadmium sulfide photoresistor commonly used, he is made by semi-conducting material.Photo resistor is very approaching to the response of visible light (0.4~0.76) μ m with human eye to the sensivity (being spectral characteristics) of light, as long as the light that human eye can be experienced all can cause his change in resistance.During the design light-operated circuit, all use filament bulb (bulb) light or available light to make the control light source, design is greatly simplified.
Wherein, thermally sensitive resister is a class of end instr, is divided into positive temperature coefficient thermistor (PTC) and negative temperature coefficient thermistor (NTC) according to the temperature factor difference.The typical feature of thermally sensitive resister is to responsive to temperature, shows different resistance values under the different temperature.Positive temperature coefficient thermistor (PTC) resistance value when temperature is high more is big more, and negative temperature coefficient thermistor (NTC) resistance value when temperature is high more is low more, and they belong to semiconductor devices.Thermally dependent resistor be exploitation early, kind is many, development is ripe sensitive components. thermally dependent resistor is made up of semiconductor ceramic material, and thermally dependent resistor is to use semi-conducting material, mostly is negative temperature coefficient greatly, and promptly resistance reduces with the temperature increase.Temperature traverse can cause big resistance to change, so he is the sensitiveest temperature sensor.But the linearity extreme difference of thermally dependent resistor, and much relations are arranged with production technology.Maker can not give standardized thermally dependent resistor curve.The thermally dependent resistor volume is very little, and is also fast to the response of temperature traverse.But thermally dependent resistor need use current source, and small size also makes him very responsive to self-heating error.
Wherein, solar storage battery is " storage battery " application in solar energy power generating, and that adopts at present has plumbic acid maintenance-free battery, common lead acid accumulator, four kinds of colloid storage battery and alkaline nickel cadmium accumulators.The domestic solar storage battery that is widely used at present mainly is: plumbic acid maintenance-free battery and colloid storage battery, this two classes storage battery, because its intrinsic " exempting from " maintenance characteristics reaches the less pollution characteristics of environment, be well suited for being used for the solar power supply system of dependable performance, particularly unattended workstation.Solar storage battery should possess following characteristic: 1, reasonable dark circulation ability has well to overcharge and cross exoergic power; 2, the long life, the long-life batteries that special technological design and colloidal electrolyte guarantee; 3, be suitable for different environmental requirements, as high height above sea level, high temperature, the battery that can both normally use under the different condition such as low temperature.
