Infrared (IR) proximity sensors have become an integral part of modern technology, providing reliable and efficient means to detect objects in close range. These sensors work by emitting infrared light and then measuring the reflection of this light from the target object. The time it takes for the light to bounce back and be detected helps determine the distance of the object. This principle allows IR proximity sensors to measure distances with remarkable precision and speed. One of the key advantages of these sensors is their non-contact nature, which makes them ideal for applications where mechanical parts cannot come into direct contact with the object being measured. Their ability to operate in various lighting conditions and environments further enhances their versatility.
