This is low cost LDR (Light Dependent Resistor). Basically it is a light sensitive resistor, the resistance will decrease when the surface is expose to light. It is widely used to detect Day or Night, example in automatic car porch light. It is nonlinear sensor, when it is not expose to light, the resistance can goes up to 500K ohm, but from our testing, in normal room condition, it will be 10 to 20K ohm when the light is not illuminate. When light is activated, the resistance drops to 1K or less.

Features:

  • Use as a resistor, just two terminals, no polarity
  • Small size LDR
  • Resistance decreases when it is expose to higher light intensity
  • Normally use with another Resistor as voltage divider

What is the resistor model needed?
( Jayden, 20/02/2020 )
Hi, it depends on the requirement. For further inquiry, you may drop an email to support@cytron.io Thanks :)
What is the specific model for this LDR? ( Tan Zhong Ming , 05/10/2019 )
Hi! There's no specific model for this item Thanks :)
what is the dimension of this LDR? ( sylvester, 13/04/2019 )
Hi, this is 5mm LDR.
what is the input voltage for this sensor? ( Lost, 27/03/2015 )

The LDR is just a resistor which its resistant will change according to the light brightness. Thus there is no voltage rating for this sensor.
