proximity detection

Proximity detection is a technology that identifies when objects or people are near each other. It uses sensors like infrared, ultrasonic waves, or radio frequency signals to measure distance or detect presence without direct contact. This technology enables devices to respond automatically—such as turning on lights when someone enters a room or unlocking a phone when it's close to your face—improving convenience and safety. Essentially, proximity detection helps systems sense nearby objects or individuals and adjust their behavior accordingly, making interactions more intuitive and efficient.
