In 2020, the new crown pneumonia epidemic has caused products such as forehead thermometers and sensors that are usually unpopular or even unknown to appear. From crazy reselling to now gradually cooling down as the epidemic dissipates. As the core component of the forehead thermometer, how should the infrared sensor develop?
The infrared sensor is the core component of the forehead thermometer. With the increasingly serious and complex changes in the epidemic situation, the infrared sensor has become a hard-to-find product in the market. Why is infrared sensor so scarce?
First of all, the radiation characteristics of the infrared sensor, the size of the radiation energy, and the wavelength distribution are closely related to the surface temperature of the object. Conversely, by measuring the infrared energy radiated by the object itself, its surface temperature can be accurately predicted. This is the mechanism of infrared radiation temperature measurement.
Secondly, the market determines the supply and demand for infrared sensors. As one of the important detection equipment for epidemic screening, diagnosis, and prevention and control, the forehead thermometer has the advantages of safety, speed, high accuracy, and intuitive readings, and has been widely used in medical, public health, and other scenarios.
