Thermal infrared sensor

A thermal infrared sensor detects infrared radiation, which is a form of heat emitted by objects. Everything with a temperature above absolute zero emits some heat energy—in the form of infrared light—that can be measured. These sensors can identify temperature differences between objects or areas without direct contact. They are commonly used in applications like night vision devices, building insulation assessment, medical thermography, and search-and-rescue operations, providing visual or data-based insights into heat patterns and temperature variations in various environments.
