3.2 Intended use
The multifunctional infrared thermometer is intended for
measuring human body temperature. It has two measurement
modes: the forehead mode for people of all ages and the ear mode
for people above the age of three months.
3.3 Principle
The infrared temperature sensor collects infrared energy emitted
by the eardrum in the ear canal or the skin of the forehead. After
being focused by a lens, the infrared energy is converted into a
temperature reading by the thermopiles and measurement circuits.
