What is the full form of the LDR Sensor?

(a) Lithium Diode Resistor

(b) Light Diaphragm Resistor

(c) Lithium Disk Resistor

(d) Light Dependent Resistor

I got this question in a job interview.

This key question is from LDR Sensor in section Interfacing of Sensors, Actuators, and Other Modules of Arduino

Correct option is (d) Light Dependent Resistor

Explanation: An LDR is called a Light Dependent Resistor. It is also called a photo-resistor or a cadmium sulfide cell. It is a photocell that works on the principle of photo-conductivity. It’s resistance value decreases when the intensity of light decreases and vice-versa.
