Which component converts a sensor's output into digital data for processing?

The device that turns a sensor’s analog output into digital data for processing is the analog-to-digital converter. Sensors create continuous signals that vary with the measured quantity. The ADC samples this continuous signal at discrete moments and converts each sample into a binary value, offering a chosen resolution (bits) and sampling rate. This digital representation is what a microcontroller or digital processor can read, process, store, or transmit. A DAC would do the opposite—take digital data and create an analog signal, not convert to digital. An instrumentation amplifier conditions and amplifies the signal but doesn’t change it into digital form. A transmitter sends data onward, but the actual conversion to digital data happens with the ADC.
