A digital thermometer for the bathtub works by using a temperature sensor to measure the water temperature. The sensor is usually located at the end of a probe that is placed in the water. The sensor then sends the temperature data to a digital display unit, which shows the current temperature of the water. Some digital thermometers also have additional features such as alarms for when the water reaches a certain temperature, or memory functions to track temperature changes over time. **
