Description
Light Dependent Resistor is a special type of resistor used for the detection of light. As it is a type of resistor hence it doesn’t have any polarity and can be connected in any direction. LDR provides high resistance of several Mega Ohm in the absence of light but as the light starts striking on its surface the resistance offered by the LDR gradually decreases to a few Ohm. It is widely used in smart street lights, automatic headlight dimmer, automatic rearview mirror, etc. LDR is often termed as Photoresistor, Photoconductor, and Photocell.
