The infrared temperature measurement function of this mobile phone can measure the temperature of an object without direct contact with it, and can keep the distance between two and three centimeters, which is safer and more sanitary to use and widely used. For example, we can use it to measure body temperature, water temperature, etc. We don't have to worry about polluting water. Moreover, it is proved by experiments that its infrared temperature measurement function is more accurate.
Then, many friends will ask, what is the principle of this infrared temperature measurement function? Is there radiation? Is it harmful to human body? Is there a security risk? Let's explore together.
Did you feel deja vu when you first touched this infrared temperature measuring function?
In fact, the principles of many of our high-tech inventions are derived from nature. For example, the submarine was invented according to the swim bladder of fish. 1680, the Italian inventor Borrielli observed the ups and downs of fish and found that fish realized the ups and downs of their bodies by contracting and expanding the swim bladder. So what is the basis of this infrared temperature measurement function? Yes, it is the buccal fossa organ of the viper.
Agkistrodon halys All poisonous snakes have a buccal fossa, which is located between the eyes and nose, in front of the eyes, and determines their position by receiving infrared rays generated by the body temperature of the prey, so it is also called a thermal sensor. It is found that any object whose temperature is higher than absolute zero will continuously emit infrared electromagnetic waves to its surroundings. The buccal fossa can judge the exact position of its prey by receiving this infrared wave, and its temperature recognition error is only 0.002℃, with high accuracy and precision, which leads to that this snake can always bite its prey quickly despite its poor eyesight.
The application of this discovery to science and technology has brought us a lot of convenience, such as thermal imaging is the basic principle. Huawei has brought this technology into our real life and brought it to most of us, making it more popular and widely used.
Like the snake's cheek pit principle, when measuring the temperature of an object, the infrared sensor receives the infrared electromagnetic wave emitted by the object, converts it into a voltage that can be collected, and then calculates the temperature of the object through a certain algorithm. Because the infrared sensor only receives infrared electromagnetic waves and does not emit them, it is still relatively safe and will not have adverse effects on the human body.
