Light Sensitive Resistor Principle and Characteristicsand Test Method

WANG Yan-hua,LIU Xi-lu(Shangqiu vacational and technical college,Shangqiu Henan 476000,China)  
Because different materials of photosensitive resistance delay characteristics are different,so their frequency characteristics are different.The use of lead sulfide frequency than cadmium sulfide much higher,but most photosensitive resistance's time delay are bigger,so it cannot be used in the occasion of rapid response requirements.According to the specific requirements of the circuit,choose the dark resistance,light resistance suitable photosensitive resistance,generally choose the dark resistance big light sensitive resistor,and dark resistance and light resistance are the bigger the better.
