Photoresistor is a resistor which made of semiconductor material, and the conductance changes with luminance variation. The photoresistor can be manufactured with different figures and illuminated area based on this characteristic. Photoresistor is widely used in many industries, such as toys,lamps,camera,etc.
5ＭＭ diameter is the most popular type for photoresistor. It widely used in measuring the light, light control. The resistance of a photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity.

A photoresistor is made of a high resistance semiconductor. In the dark, a photoresistor can have a resistance as high as several megohms (MΩ), while in the light, a photoresistor can have a resistance as low as a few hundred ohms.View More
Light dependent resistors, LDRs or photoresistors are often used in circuits where it is necessary to detect the presence or the level of light. They can be described by a variety of names from light dependent resistor, LDR, photoresistor, or even photo cell, photocell or photoconductor.View More
