This post explains for the Photoresistor.
The Part Number is GL5516.
GL5516 is Photoresistor. Photoresistor is a resistor which made of semi-conductor 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.
A photoresistor, also known as a light-dependent resistor (LDR) or photocell, is a passive electronic component that exhibits a change in its electrical resistance based on the intensity of incident light. The resistance of a photoresistor decreases as the amount of light falling on it increases, and vice versa. This property makes it a useful component in various light-sensing applications.
