A photocell changes (also called a LDR, photodetector, photoresistor, CDS or photoconductive cell) resistance depending on the amount of light it is exposed to.
Features:
- Light resistance : ~1k Ohm
- Dark resistance : ~10k Ohm
- Max voltage : 150V
- Max power: 100mW
These photocells can be used in many applications:
- Auto-focus lenses
- Exposure meters
- Contrast controls for TVs
- Dimmer or light switches
- Flame detectors
- Electronic toys
- Street lamp switches
- Optocouplers
