Infrared temperature concept Infrared temperature usually refers to the surface temperature of an object measured by infrared technology. This measurement takes advantage of the fact that all objects emit infrared radiation, even at room temperature. Infrared thermometers (or infrared thermometers) calculate an object's surface temperature by capturing this infrared radiation and converting it into an electrical signal. Working principle Infrared thermometers work based on the relationship between the infrared radiation emitted by an object and its temperature. Specifically, when an object's temperature is above absolute zero, it continuously emits infrared radiation. Infrared thermometers collect this radiation through their optical system and focus it onto the detector. The detector converts the received radiation energy into an electrical signal, which is then processed and calculated through the built-in circuit, and finally shows the temperature of the object.

Temperature and humidity sensors are most widely used in numerous fields, especially in the work of recording temperature and humidity changes in real time. Temperature and humidity sensors can be managed, analyzed and summarized scientifically and effectively according to what is recorded. The type of temperature and humidity sensor chosen varies in different applications. The following are some scenarios in which temperature and humidity sensors are used. 1.Application of temperature and humidity sensor in the subway environment Subway passenger flow is high and the amount of fresh air required varies greatly. Therefore, the air conditioning load of the subway varies greatly, and energy saving must be achieved with the help of automatic control means.   In this regard, indoor temperature and humidity sensors are installed in public areas such as station concourses and platform areas, as well as in important equipment rooms, so that the real-time temperature and humidity of the s...

With the rapid development of computer technology, the quality as well as the reliability of computers have been greatly improved. However, because computers are affected by the component parts and various other factors, they have certain requirements for the temperature and humidity of the environment in which they are used while working. 　 Not only does temperature have an effect on computer systems , but humidity also has, too high or too low, will directly affect the quality of the work of the computer system, and needs to attract the attention of the operator. In general, the computer system at work, requiring the use of the environment's optimal humidity range of 45% to 60%, while the maximum allowable range should not exceed 35% to 80%. If the humidity is too high, it will cause moisture to adhere to the surface of the computer components, so that the performance of the circuit within the machine is reduced, and even short-circuit and burn some parts. More serious is that th...
