Digital thermometers use heat sensors, typically thermistors or infrared sensors, to detect temperature changes. These sensors convert thermal energy into electrical signals, which are then processed and displayed as a temperature reading on the screen.
Temperature in a digital thermometer is determined with the help of heat sensors. Explain.

Digital thermometers measure temperature using specialized heat sensors, such as thermistors or infrared sensors. Thermistors change their resistance with temperature fluctuations, allowing for accurate readings, while infrared sensors detect the thermal radiation emitted by the object being measured.
Once the sensor detects temperature changes, it converts the thermal energy into electrical signals. These signals are then processed by the thermometer’s microprocessor and displayed on the screen as a digital temperature reading. This technology enables quick and precise measurements, making digital thermometers popular in both clinical and home settings.
