Description

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. In the dark, their resistance is very high, sometimes up to 1M?, but when the LDR sensor is exposed to light, the resistance drops dramatically, even down to a few ohms, depending on the light intensity.

Features

  • Operating voltage : 2 – 5 V
  • Dark resistance ? 1 M?
  • Light resistance ? 10 K?
  • Output type : Analog
