This Photo Resistor Module for Arduino is used to indicate the presence or absence of light and to measure light intensity.
This tiny board features a photo resistor; you do not need to connect additional resistors to get this sensor up and running. Holding the board with the pins toward you, VCC is the middle pin. Ground the right and left is the signal pin that connects on any analog pins. Widely used in cameras, solar garden lights, detectors, clock, music, cups and gift boxes.
