  • Simple LDR Circuit to Detect Light

    2016-10-22 · In the following circuit , CASE 1: When light is not incident on the LDR , it acts as a very high resistance . Due to which the voltage at the base of the transistor is too LOW to turn the transistor ON. No current flows through the emitter collector jn of the transistor and so NO CURRENT FLOWS THROUGH THE LED. CASE 2: When light is incident on the LDR …

  • Light Detector using LDR - Electronics Hub

    2021-6-5 · Transistor as a Switch Using LDR. A light-dependent resistor (LDR), such as an ORP12, is a special type of component whose resistance changes in an inversely proportional manner to the light intensity falling upon it. In the dark, its resistance increases; however in light, its resistance decreases.

  • Light detector using LDR | Hackaday.io

    Remember, the LDR resistance depends on the light you have on the room or where you are constructing that. If you have light, the LDR resistance is low so, the LED should be turned off. When you obstruct the light that focus on the LDR, the LED should light up. If for any reason your LED is always lighted up, try to chance the transistor …
