Description

LDR: Light Dependent Resistor An Light Dependent resistor (LDR) also called as photo-resist is a sensor whose output varies in proportion to the light falling on it. This is the most common type of LDR where the resistance of the LDR decreases as the light intensity of light falling on it increases i.e the resistance is inversely proportional to the light intensity falling on the LDR.
