LDR working principle and application circuit
An LDR (Light Dependent Resistor) is a sensor whose resistance changes with light intensity. It is made from a photoconductive material placed on a ceramic base with electrodes and protective coating. When light falls on the surface, more charge carriers are generated, causing the resistance to decrease. In darkness the resistance is very high ...
