Light dependent resistor is made of semiconductor material. Also name LDR, photoconductor. The electric conductivity changs by the illuminance. The illuminance is more stronger, the value of the resistance will be more weaker. With this chareter, we can produce different size to satified different requirement. We have 5MM and 12MM series.

What is the testing conditions?
Max external voltage: Maximum voltage to be continuously given to component in the dark.
Max power consumption: Maximum power at the environmental temperature 25℃.
Light resistance Irradiate by 400-600Lux light for two hours, then test with 10Lux under standard light source A(as colour temperature 2856K).
Dark resistance Refer to the resistance value ten seconds after the 10Lux light is shut up.
Light dependent resistors, LDRs or photoresistors are often used in circuits where it is necessary to detect the presence or the level of light. They can be described by a variety of names from light dependent resistor, LDR, photoresistor, or even photo cell, photocell or photoconductor.View More
A photoresistor is made of a high resistance semiconductor. In the dark, a photoresistor can have a resistance as high as several megohms (MΩ), while in the light, a photoresistor can have a resistance as low as a few hundred ohms.View More
