Contactless temperature measurement is a method used to determine the temperature of a person or object without physical contact. This technology typically employs infrared sensors that detect the heat emitted by the skin or surface. It is commonly used in medical settings, public places, and industrial applications to quickly assess temperature without the need for thermometers that require touching. This approach is particularly useful for screening individuals for fever or illness, as it allows for rapid assessments while minimizing the risk of spreading infections. Contactless temperature measurement devices are often portable and easy to use, making them ideal for various environments, including airports, schools, and hospitals.
