Product Code: WRL-190
Availability: In Stock


Description :

             A photoresistor or light dependent resistor (LDR ) is a component that is sensitive to light. When light falls upon it then the resistance changes. Values of the resistance of the LDR may change over many orders of magnitude the value of the resistance falling as the level of light increases.It is not uncommon for the values of resistance of an LDR or photoresistor to be several Megaohms in darkness and then to fall to a few hundred ohms in bright light. With such a wide variation in resistance, LDRs are easy to use and there are many LDR circuits available.

Light detecting resistor(LDR) module most sensitive to environmental light intensity is generally used to detect the ambient brightness and light intensity.
