About this itemA photoresistor or light-dependent resistor (LDR) or photocell is a light-controlled variable resistor.The resistance of a photoresistor decreases with increasing incident light intensityIn other words, it exhibits photoconductivity.item shape: roundcan be applied in light-sensitive d..

This is 8 mm size light sensor with maximum surface area which changes resistance with the change in the ambient light exposed on the surface of the sensor. LDR (Light Dependent Resistor) is a type of photocell which finds excellent use in light sensing device application, whether it is automatic ou..
