Description
- LDR (Light Dependent Resistor) 5mm LDR (Light Dependent Resistor) 5mm, Ldr, which stands for Light Dependent Resistor, is a photo resistor. Photoresistors are electronic components whose resistance changes depending on the light intensity. The LDR is made of "cadmium sulfide" (CdS), a semiconductor material that can absorb photons of light.
