Infrared sensors are electronic devices designed to detect infrared radiation emitted by objects. These sensors convert thermal energy into electrical signals, enabling systems to identify motion, temperature variations, and the presence of objects without physical contact. One of the key features of infrared sensors is their ability to operate in low-light or no-light conditions, making them highly reliable for monitoring and detection purposes. They are typically compact, energy-efficient, and capable of providing accurate measurements in real time. Infrared sensors are also valued for their fast response times and their ability to function in a wide range of environmental conditions.

According to Stratview Research, "The infrared sensor market is likely to grow at a promising CAGR of 5.1% during 2023-2028 to reach USD 1.4 billion in 2028."
