Movement can be detected by various devices and technologies, including motion sensors, cameras, and accelerometers. Motion sensors, such as passive infrared (PIR) sensors, detect changes in heat or infrared radiation from moving objects. Cameras equipped with computer vision algorithms can identify and track movement in their field of view. Additionally, accelerometers measure changes in velocity and orientation, allowing them to detect movement in devices like smartphones and fitness trackers.
