Mid-IR sensors are electronic devices that emit radiation tosense the surrounding object. They are widely used for chemical and gasdetection, thus increasing the demand for these sensors in the chemical and oiland gas industries. Moreover, Mid-IR sensors are being used at airport,hospitals, and other locations to detect body temperature during COVID-19pandemic. In a defined angle range, the sensor elements detect heat radiation(infrared radiation) that changes over time and space due to the movement ofpeople. This exciting technology allows consumers to track, inspect, and detectpotential temperature changes in a wide variety of applications. Mid-waveinfrared technology is a new infrared scanning technology that utilizes theprinciple of the refraction of light to capture invisible light.
An active infrared sensor is a thermal sensor that alsomeasures the infrared radiation emitted by objects within its field of vision.They are most commonly utilized in PIR-driven automatic lighting systems. PIRdetectors are widely used in security alerts and other automated lightingapplications. Mid-IR sensors are used for manyapplications, including medical imaging, asset tracking, surveillance, andindustrial work areas, among others. There are two types of passive infraredsensors, those that can only sense infrared radiation and those that can alsodetect microwave frequencies. The former is known to be more efficient due tothe shorter wavelength it can detect, which is why these wavelengths are alsoemployed in military applications.
