It is a 8 mm sized photoresistor - light dependent 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 outdoor light ON/OFF switch or Indoor automatic light switching. The sensor works best in both Light and dark region.

Light Resistance: 10K Ohm @ 10Lux

Size:  8 mm (dia.)

Dark Resistance: 1.0M Ohm @ 0 Lux

Max Voltage: 150 volt

Max Power: 100 mW
