Infrared technology refers to the use of infrared radiation, which is a type of electromagnetic radiation with wavelengths longer than visible light. This technology is commonly used in various applications, including thermal imaging, remote controls, and night vision devices. Infrared sensors can detect heat emitted by objects, making them useful for monitoring temperature changes and identifying living beings in low-light conditions. In addition to its applications in security and surveillance, infrared technology is also utilized in industries such as healthcare, where it aids in non-invasive temperature measurement. Furthermore, it plays a role in communication systems, allowing for wireless data transmission over short distances.
