Light Dependent Resistor - LDR. Two cadmium sulphide (cds) photoconductive cells with spectral responses similar to that of the human eye. The cell resistance falls with increasing light intensity. This memory effect can be minimised by storing the LDRs in light prior to use.

Application of CdS resistors specific designs also available including different photo resistance and response time specifications adjusted to resistance requirements.
Cadmium-Sulfide), light-dependent resistors ( LDR ), and photoresistors.
Ambient light like… Ambient light. The photoresistor can be manufactured with different figures and illuminated area based on this characteristic. Photoresistor is widely used in many industries, such as toys,lamps ,camera,etc. If light falling on the device is of high enough frequency, photons .

The Proximity detection feature provides. The proximity engine features offset adjustment registers to compensate for system offset caused by unwanted IR energy reflections appear- ing at the sensor. Dark Resistance: measured seconds after pulsed Iux.
Gamma Characteristic: between 10 . Information in this technical datasheet is believed to be correct and reliable. However, no responsibility is assumed for possible inaccuracies or omission. MΩ sec after removal of light. In combination with Universal sensor switching module SENSW-.
The LDR -probe is suitable for many applications in which the switching action is dependent on light intensity. Photocells are sensors that allow you to detect light. For that reason they often appear in toys, gadgets and appliances.
As the amount of light falling on this LDR increases, its resistance decreases. The light detector itself is just 5mm in diameter. The resistance of an LDR may typically have the following resistances. Photosensitive sensor module is the most sensitive for the environmental light intensity and it is generally used for detecting the ambient brightness and intensity of the environment. Without light intensity it will not reach the threshold resulting for low level output but, when the external environment light intensity exceeds the . With develop- ment and manufacturing centers around the worl . Typical light resistance = 2K – 4K.
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.
