Infrared thermometry is a technology that uses infrared radiation to measure the temperature of objects. The basic principle is based on the infrared radiation emitted by an object depending on its temperature. Infrared detectors convert the captured infrared radiation into electrical signals, which are then converted into temperature readings using physical formulas such as Stefan-Boltzmann's, based on the emissivity of the object and the intensity of the radiation being measured. The advantages of infrared thermometry include non-contact measurement, fast response, and suitability for high temperature or moving objects. Disadvantages include dependence on emissivity, environmental interference and possibly limited measurement accuracy in some cases. Place your palm above the probe, and the infrared thermometer will measure the temperature and broadcast it to measure the temperature.
