What can detect light? The most common light sensor type that’s used in a light sensor circuit are photoresistors, also known as a light-dependent resistor (LDR). Photoresistors are used to simply detect whether a light is on or off and compare relative light levels throughout a day.
Does a light sensor detect an object? Reflective and through-beam sensors create a beam of light and detect any opaque object that breaks the beam. Laser sensors can create a beam of light 50 meters or longer.
