Datasheet of ldr sensor

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.

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. This memory effect can be minimised by storing the LDRs in light prior to use.

All pages on the resistor guide about ldr datasheet are collected on this page.

Find light dependent resistors for your DIY or trade optoelectronics project. Dark Resistance: measured seconds after pulsed Iux. Gamma Characteristic: between 10 . LED driver input for proximity IR LE constant current source LED driver. LED Cathode, connect to LDR pin when using internal LED driver circuit.

They are often referred to as CdS cells (they are made of Cadmium-Sulfide), light -dependent resistors ( LDR ), and photoresistors. The photoresistor can be manufactured with different figures and illuminated area based on this characteristic. Typical light resistance = 2K – 4K.

Photoresistor is widely used in many industries, such as toys,lamps ,camera,etc. It is called light sensor or photocell or LDR (light dependent sensor ) or photo- resistor. Photo resistors, also known as light dependent resistors ( LDR ), are light sensitive devices most often used to indicate the presence or absence of light, or to measure the light intensity.

A photocell changes resistance de. In the dark, their resistance is very high, sometimes up to 1MΩ, but when the LDR sensor is exposed to light, the resistance . 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 . The light sensor , also known as the light dependent resistor ( LDR ). Therefore, please consult the ORPdatasheet. When the light level increases, the resistance of the LDR will fall and the voltage across it falls as well. Using the characteristics of different shapes and made by light area of photoconductive resistance.

Photoconductive resistance is widely applied in toys, lamps and . The resistance decreases as the intensity of incident light increases, and vice versa. Coated With epoxy, good reliability, high sensitivity, fast response, good . R ldr is related to the voltage measured over it, reading the Voltage over it, can be used to calculate the Rldr and thus the Lux level.
