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). Features: * Light resistance : ~1k Ohm * Dark resistance : ~10k Ohm * Max voltage : 150V * Max power: 100mW Dimensions: * 2 x 4 x 5mm * 4mm between pins * 31mm lead length Documents: * Datasheet * Hookup Guide * Bildr Tutorial https://elecena.pl/product/800774/mini-photocell 2009-01-29 https://elecena.pl/product/800774/mini-photocell 2016-11-25 https://elecena.pl/product/800774/mini-photocell 2016-11-28 https://elecena.pl/product/800774/mini-photocell 2016-11-29 https://elecena.pl/product/800774/mini-photocell 2016-12-09 https://elecena.pl/product/800774/mini-photocell 2016-12-13 https://elecena.pl/product/800774/mini-photocell 2017-11-10 https://elecena.pl/product/800774/mini-photocell 2017-11-13 https://elecena.pl/product/800774/mini-photocell 2017-11-24 https://elecena.pl/product/800774/mini-photocell 2017-11-28 https://elecena.pl/product/800774/mini-photocell 2018-05-05 https://elecena.pl/product/800774/mini-photocell 2018-11-21 https://elecena.pl/product/800774/mini-photocell 2018-11-27 https://elecena.pl/product/800774/mini-photocell 2019-12-09 https://elecena.pl/product/800774/mini-photocell 2019-12-14 https://elecena.pl/product/800774/mini-photocell 2022-02-22 https://elecena.pl/product/800774/mini-photocell 2025-04-12 https://elecena.pl/product/800774/mini-photocell 2025-04-14
