-The resistance of 20mm GL20528 Light Sensitive Photoresistor LDR changes with the change in the ambient light exposed on the surface of the sensor.
-As the light on the sensor increases then the resistance across the two leads decreases.
-Light Dependent Resistor is a type of photocell which finds excellent use in light sensing device application, whether it is automatic outdoor light ON/OFF switch or indoor automatic light switch; moreover, the 12mm LDR or photoresistor sensor works best in both light and dark regions.
-The photo-resistor is a staple of electronics.
-If you need a way to sense the level of ambient light, then there is no easier way to do it without an LDR/photo-resistor.
-Two Cadmium Sulphide PhotoConductive Cells with spectral responses similar to that of the human eye.
-Cell resistance falls with increasing light intensity.
-Applications of this product include smoke detection, automatic lighting control, batch counting, and burglar alarm systems.
-Furthermore, some of the applications are given below.
