Common types of light sensors are photodiodes, photoresistors, phototransistors, and photovoltaic light sensors. Light Sensors are photoelectric devices that convert light energy (photons) whether visible or infra-red light into an electrical (electrons) signal What Are Light Sensors? A Light Sensor generates an output signal indicating the intensity of light by measuring the radiant energy that exists in a. They detect the presence or absence of light and can measure its intensity, wavelength, and other properties. It's a special type of resistor that varies its resistance with the amount of light that falls on it.
