motion sensing

Motion sensing refers to the technology that detects movement within a specific area. It works by using sensors like infrared, ultrasonic, or microwave to identify changes in the environment caused by objects or people. When motion is detected, these sensors send signals to activate devices such as lights, alarms, or cameras. This technology enables efficient energy use, enhances security, and automates various functions by responding only when movement occurs. Overall, motion sensing systems improve convenience and safety by reliably identifying activity without requiring constant manual intervention.
