5mm 5537 Light Dependent Resistor

This Light Dependent Resistor (LDR) can be used to easily measure ambient light with your Arduino or other board with analogue input. in the dark and at low light levels, the resistance of an LDR is high and little current can flow through it.

Q & A

5mm 5537 Light Dependent Resistor and Photoresistors come in many types. Inexpensive cadmium sulfide (CdS) cells can be found in many consumer items such as camera light meters, clock radios, alarm devices (as the detector for a light beam), nightlights, outdoor clocks, solar street lamps, and solar road studs, etc.

What does a light-dependent resistor do?
LDRs (light-dependent resistors) are used to detect light levels, for example, in automatic security lights. Their resistance decreases as the light intensity increases:
