This module adapted for the arduino is a light sensor. The resistance of the LDR cell decreases as the light intensity increases.
On the contrary in a dark environment, the resistance of the LDR cell increases accordingly. Characteristic: - 3-pin connector: 1- GND
2- VCC
3- analog output - the voltage depending on the light
- Supply voltage: 3.3 V-5VDC
- PCB size: 19x15x8 mm
