The ear thermometer is a commonly used tool for measuring body temperature in families preparing for pregnancy. Its working principle mainly includes the following parts:
1. Infrared temperature measurement technology: Ear thermometer The thermometer uses infrared temperature measurement technology, which measures body temperature by sensing infrared radiation emitted from the human ear. The eardrum of the human body is a radiant heat source, and an ear thermometer can calculate the body temperature by detecting this heat radiation.
2. Detection device: The ear thermometer is equipped with a non-contact detection device inside, usually an infrared sensor. When the ear thermometer is pointed at the ear, the infrared sensor receives the infrared radiation emitted by the eardrum and converts it into an electrical signal.
3. Thermal radiation calculation: After obtaining the electrical signal, the ear thermometer will analyze and calculate the body temperature through the internal calculation program. Specifically, it compares the received electrical signal with the known body temperature range of the human body, and then determines the body temperature based on the comparison results.
4. Temperature display: Finally, the ear thermometer will display the measured body temperature results to the user through the display screen or other means. Usually, the display of the ear thermometer will directly display the measurement results so that users can easily understand their body temperature.
In general, the ear thermometer senses the infrared radiation emitted by the eardrum, converts it into an electrical signal, and analyzes and calculates the body temperature through an internal calculation program. Display the measurement results to the user. Its working principle is simple and efficient, and its non-contact feature also makes it more convenient and hygienic to use. Families preparing for pregnancy can use ear thermometers to monitor body temperature at any time, detect physical abnormalities in time, and prepare for pregnancy.
