The function of a sensor in an electronic device is to detect and measure a specific physical input or environmental condition such as light, temperature, pressure, motion, or proximity. It converts these physical quantities into electrical signals that can be processed by the device's microcontroller or processor. Sensors enable devices to perceive and respond to their surroundings, providing valuable information for decision-making and control purposes.
