An infrared temperature sensor is a sensor that can measure the temperature of an object's surface by sensing the energy of infrared radiation on the surface of an object. It adopts non-contact temperature measurement technology, which can not only avoid the defects such as physical interference and measurement errors caused by traditional temperature sensors, but also has the advantages of high precision, long life and fast response, and has been widely used in medical, industrial, semiconductor and other fields. This article summarizes some information and hopes to provide readers with valuable references.
Its working principle is based on the infrared radiation energy of an object's surface to measure its temperature. The specific process is as follows:
1.Infrared emitters emit a specific frequency of infrared light, which has energy.
2.Infrared radiation of objects: The temperature of the surface of an object causes the object to emit infrared radiation, the intensity of which is proportional to the temperature.
3.Reflection of infrared light: When infrared light hits the surface of an object, some of it is reflected back to the sensor.
4.Reception and interpretation: The infrared receiver in the sensor receives the reflected light and converts it into an electrical signal.
5.The temperature of the object is calculated based on the intensity of the received infrared light.
Infrared temperature sensor applications.

In the industrial field, infrared temperature sensors are mainly used in industrial heating, laboratory temperature measurement, gas thermodynamics, high-speed moving object temperature measurement, metallurgical furnace temperature measurement, etc. For example, for the metallurgical industry in high-temperature environments, infrared temperature sensors can be used to measure the temperature in the furnace in real time, improving production efficiency and safety.
2. The application of infrared temperature sensor in the medical field.
In the medical field, infrared temperature sensors are widely used to measure human body temperature. Different from traditional oral cavity, armpit and other measurement methods, infrared temperature sensors can achieve non-contact measurement, avoiding the possibility of infectious diseases. In addition, infrared temperature sensors can also be used to measure the temperature of items such as operating rooms, surgical instruments, medicines, etc., to ensure the safety and hygiene of medical processes.
3. The application of infrared temperature sensor in the agricultural field.
In the agricultural field, infrared temperature sensors can be used to measure crop surface temperature, soil temperature, animal body temperature, etc. By measuring the temperature difference in different parts, it is possible to better grasp the health status of crops and animals, and provide decision support for agricultural production. For example, for the production of greenhouse crops, infrared temperature sensors can be used to measure the surface temperature of plants, adjust the indoor temperature, and improve crop yield and quality.
4. Thermal imaging.
In the field of thermal imaging, infrared temperature sensors are used to capture the thermal radiation energy of an object's surface and convert it into a visual thermal image. This technology is widely used in building materials, machinery and equipment, electronic products and other fields to facilitate the detection of faults and improve work efficiency.
5. Automotive electronics.
In the field of automotive electronics, infrared temperature sensors can be used to measure the temperature of the air conditioning outlet in the car, detect key parameters such as engine water temperature and oil temperature, and can also be used to monitor the thermal changes of the braking system.
