Led Control

  1. May 28, 2008 #1
    Hi I would like to know if there is a sensor available in the market that would help control the intensity of light given out by a white LED, taking into account the light coming from the surrounding ambient light. As an example I am trying to implement a project in which I would have to control the intensity of light given out from a white LED which is placed above a computer monitor screen, based on the intensity of light given out from the computer screen, I would have to control the LED light. I would also like to know if the sensor is not available in the market how am I supposed to go about implementing this project.

    A photodiode generates current due to the light intensity that it senses, maybe u can try it.
