How does a thermometer work?
Electronic thermometers utilize the definite relationship that exists between the physical parameters of certain substances, such as resistance, voltage, current, etc., and the ambient temperature to display the body temperature in digital form.
The human body temperature varies with the time of day, and the human body temperature is lower in the early morning and slightly higher in the late afternoon. So it is normal to see a slight difference in temperature measurements throughout the day.
All electronic thermometers have an accuracy of at least 0.1°C; F (0.05°C), so they can be used as a basic thermometer.
