5mm LDR (Light Dependent Resistor) Proximity reliable performance5mm LDR (Light Dependent Resistor) A 5mm LDR photoresistor sensor is made of a high resistance semiconductor. If light falling on the device is of high enough frequency, photons absorbed by the semiconductor give the bound electron enough energy to jump into the conduction band. The resulting free electron (and its hole partner) conduct electricity, thereby lowering resistance. A photoelectric device can be either intrinsic or extrinsic. An intrinsic
