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