Products/Services for What Is A Light Dependent Resistor

  • Light Sensor Chips-Image
    Light Sensor Chips - (32 companies)
    Light sensor chips convert light into electrical signals which are then conditioned to produce a desired electrical output. They are sometimes called light-to-frequency chips, light-to-voltage chips, or ambient light sensors. Light sensor chips...

    Light Guides - (137 companies)
    Light guides conduct the flow of light from a light source to a point of use in areas that are too small or too hazardous to permit the installation of a light bulb. There are two basic types of light guides: liquid and fiber optic. Light guides...

Conduct Research

The light barrier is in itself a relatively simple construction. Most of us are probably familiar with it from our physics lessons or from electronics kits, where the apparatus consists of a light source, usually in the form of a light bulb or LED, and a receiver element, mostly a light-dependent...
