   we’ll be discussing the basics of infrared sensors, how they work, and their applications. Chapter 1: Introduction to Infrared Sensors ·        What is an infrared sensor? An infrared (IR) sensor is an electronic device used to measure and detect infrared radiation in its surrounding environment An IR sensor can measure the heat of an object as well as detects the motion . ·        How does an infrared sensor work? An IR sensor can detect changes in the amount of infrared radiation impinging upon it, which varies depending on the temperature and surface characteristics of the objects in front of the sensor . These types of radiations are invisible to our eyes, which can be detected by an infrared sensor. The emitter is merely an infrared LED (Light Emitting Diode), and the detector is simply an infrared photodiode sensitive to infrared light of the same wavelength as the IR LED. When infrared light strikes...
