Huge Diam 5mm Homemade Photoresistor φ5 Series for Led Dimmer


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.
