Description, Price, Minimum Light Resistance, Dark Resistance, Typical Fall Time , Typical Rise Time, Resistor Material, Number of Pins, Mounting Type, Package Type, Maximum Light Resistance, Maximum Operating Temperature, Minimum Operating Temperature, Light Resistance Range, Operating . Light dependent resistors or photoresistors decline in resistance when the light intensity increases. Light Dependent Resistor ( LDR ), Photo Resistors (CDS) provides the mechanical data, electronic characteristics and test conditions in terms of 5mm, 12mm, and 20mm. Application of CdS resistors specific designs also available including different photo resistance and response time specifications adjusted to resistance . The resistance decreases as the intensity of incident light increases, and vice versa.

Two cadmium sulphide(cds) photoconductive cells with spectral responses similar to that of the human eye.

The cell resistance falls with increasing light intensity.

Applications include smoke detection, automatic lighting control, batch counting and burglar alarm systems. Photo Light Dependent Resistors - LDR at Farnell element14. A photoresistor can be applied in light-sensitive detector circuits, and light-activated . If light falling on the device is of high enough frequency, photons . This memory effect can be minimised by storing the LDRs in light prior to use.


Light storage reduces equilibrium time to reach steady resistance values. The LabVIEW VI that reads the voltage across the LDR and converts the voltage to lux is called EMANT300 . Photocells are sensors that allow you to detect light. For that reason they often appear in toys, gadgets and appliances.

Specification : Max Voltage (DC): 150V Max Power Consumption: 100mW. Hence, they are light sensitive devices. They are also called as photo conductors, photo conductive cells or simply photocells.


The cadmium sulfide (CdS) or light dependent resistor ( LDR ) whose resistance is inversly dependent on the amount of light falling on it, is known by many names including the photo resistor , photoresistor, photoconductor, photoconductive cell, or simply the photocell. Nearly all photocells will have slightly different specifications , although they all pretty much work the same. CdS cells, photoresistors, LDR (light dependent resistor ).
