The LDR sensor module detects the intensity of light. It is linked to both analog and digital output pins on the board, which are designated AO and DO, respectively. When there is light, the resistance of the LDR decreases in proportion to the intensity of the light. The lower the resistance of LDR, the greater the intensity of light. A potentiometer knob on the sensor may be changed to modify the sensitivity of the LDR to light.
