Mini Photocell — LDR Light Sensor

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 OhmDark resis­tance : ~10k OhmMax volt­age : 150VMax pow­er: 100mWDimen­sions:2 x 4 x 5mm4mm between pins31mm lead lengthDoc­u­ments:DatasheetBil­dr Tuto­r­i­al
