What technology does a light sensor use to process its signals?

A light sensor employs an Analog-to-Digital Converter (ADC) to process its signals because it typically produces an analog signal in response to light intensity. The ADC is essential for converting this analog signal, which varies continuously, into a digital signal so that it can be read by a microcontroller or other digital devices. By converting the analog information about light levels into a digital format, the light sensor enables digital systems to interpret and respond to varying light conditions effectively. This process allows for accurate measurement, decision-making, and integration within electronic systems.
