A photoresistor or LDR 5mm - Light Dependent Resistor is a resistor whose resistance decreases with increasing incident light intensity; in other words, it exhibits photoconductivity.A photo-resistor is made of a high resistance semiconductor. If light falling on the device is of high enough frequen..

The Light Sensor generates an output signal indicating the intensity of light by measuring the radiant energy that exists in a very narrow range of frequencies basically called “light”, and which ranges in frequency from “Infra-red” to “Visible” up to “Ultraviolet” light spectrum.Features of Light S..
