A digital thermometer functions as a temperature-measuring device utilizing electronic sensors to detect and present temperature readings in a digital format. In contrast to traditional mercury or analog thermometers, digital counterparts display temperature values numerically on a digital screen. Typically composed of a temperature sensor, microprocessor, and display screen, digital thermometers come in various types, such as oral, ear, forehead, rectal, and infrared models, each tailored for specific applications. Widely employed in both medical and non-medical environments, they serve to measure body temperature and monitor environmental temperatures.
