Exploring Infrared Sensors: Types, Applications, and Principle
1. Active Infrared Sensors: These sensors emit their own infrared light and detect the reflected light.They are commonly used in proximity sensors and certain types of motion detectors. An example is the IR LED and photodiode pair, which measures changes in the reflected light to determine the presence of objects.
What is an IR sensor? - Fierce Electronics
Jul 29, 2019 · An infrared (IR) sensor is an electronic device that measures and detects infrared radiation in its surrounding environment. Infrared radiation was accidentally discovered by an astronomer named William Herchel in 1800.
Infrared Sensors Basics - Types and comparisons of infrared sensors
Infrared sensors can be largely divided into "thermal" and "quantum" types based on their operational principles. Thermal sensors convert infrared rays into heat which is then changed to a resistance change and thermoelectromotive force to extract the output.
