Details: Light ambient sensor made by a photoconductive cell.
The sensor varies their internal resistance if targeted by a light beam. His resistor is something in the range of megaohms when placed in the dark and falls into the 10k ohms range when placed at the direct light.
It can be connected to an Arduino analog input with an external series resistor.
Operating temperature: from -40 to 75 C.
