WebThe Light-Dependent Resistor (LDR) A light-dependent resistor (LDR) is a non-ohmic conductor and sensory resistor. Its resistance automatically changes depending on the light energy falling onto it (illumination) As the light intensity increases, the resistance of an LDR decreases. Resistance of an LDR depends on the light intensity falling on it.
