10mm LDR - A Light-Sensitive Resistor

The LDR, an acronym for Light Dependent Resistor, is a type of photoresistor. Photoresistors are specialized electronic components that exhibit a change in resistance based on the intensity of light they are exposed to.

Composition of the LDR

The LDR is constructed using a semiconductor material known as "cadmium sulfide" (CdS). This material possesses the unique ability to absorb light photons.

Functionality of the LDR

The primary function of the LDR is to alter its resistance in response to changes in light intensity. This characteristic makes it an essential component in various electronic devices and systems.
