A photocell is made up of a semiconductor, the working of which is dependent on
the intensity of incident light. When the amount of light exceeds a certain ...
Photocells are used in automatic night lights and in street lamps that turn
themselves on ... In operation, a photocell acts like a light sensitive resistor with a
Nearly all photocells will have slightly different specifications, although they all
pretty much work the same. If there's a datasheet, you'll want to refer to it.

Dec 18, 2009 ... The photocell came off a street light that was installed in 1995. It was removed at
work last week. The light at the top is the 'fake sun'.
... you would wire a CdS cell directly to a relay (see How Relays Work), so that a
lot of ... So when light shines on the photocell, it turns the transistor on, which ...
Light Immunity: The maximum limit of an incandescent light or sunlight. Beyond
this limit, the photocell may not work correctly due to interference on the receiver.
