Introduction: As we Know infrared is a electromagnetic radiation having a wavelength just greater than that of the red end of the visible light spectrum but less than that of microwaves. Infrared radiation has a wavelength from about 800 nm to 1 mm, and is emitted particularly by heated objects. And a Infared proximity sensor is an electronic sensor capable of detecting the presence of nearby objects without physical contact. It emits an electromagnetic field or a beam of electromagnetic radiation (for example: infrared) and then looks for changes in the return signal or field.
When anything comes in the range of Proximity sensor it flash out infrared beam and monitors reflections. When sensor senses reflections it confirms that there’s an object nearby. Learn more about infrared proximity sensor here.
