This is a very small light sensor. A photocell changes (also called a photodetector, photo resistor, CdS or photoconductive cell) resistance depending on the amount of light it is exposed to. These little sensors make great ambient light triggers (when light in the room turns on, do something).


  • Light resistance : ~1k Ohm
  • Dark resistance : ~10k Ohm
  • Max voltage : 150V
  • Max power: 100mW


  • 2 x 4 x 5mm
  • 4mm between pins
  • 31mm lead length

Easy to use photocell
Saturday, 11 January 2014  |  Chris

I'm using this photocell with an Arduino/LCD display that is in my bedroom. The display is far too bright at night so, with this photocell, my Arduino now switches off the display when the lights go out.
