3mm LDR

Description

Description

LDRs or Light Dependent Resistors are very useful especially in light/dark sensor circuits. Normally the resistance of an LDR is very high, sometimes as high as 20000 ohms, but when they are illuminated with light resistance drops dramatically.

Photoconductive cells are sensors that allow you to detect light. They are small, inexpensive, low−power, easy to use, and don’t wear out. NTEs light−dependent resistors (LDR) are photoresistors whose resistance decreases with increasing incident light intensity. In other words, when it is dark, they have a high electrical resistance and when it is light, their electrical resistance is low
