Mini Photocell Light Sensor
Light resistance: ~1k Ohm
Dark resistance: ~10k Ohm
Max voltage: 150V
Max power: 100mW
The Mini Photocell Light Sensor is a very small photocell. A photocell changes (also called a photo detector, CdS or photoconductive cell) resistance depending on the amount of light it is exposed to. These little sensors make great ambient light triggers.
