Photoresistor is a resistor which made of semi-conductor material, and the conductance changes with luminance variation. The photoresistor can be manufactured with different figures and illuminate area based on this characteristic.
Applications:
1.Switch, Light control, Electronic toy
2.Light control lamp
3.Photoelectric control, Industrial control
4.Camera automatic photometry, Annunciator
Technical parameter for 7mm photocell sensor
