Proximity Sensing

Proximity sensing is technology that detects the presence or absence of nearby objects without physical contact. It uses sensors like infrared, ultrasonic, or electromagnetic fields to identify when an object is close. This is commonly used in devices such as smartphones to turn off the screen when held to your ear, or in parking sensors to alert drivers of nearby obstacles. Proximity sensors enable devices to interact intelligently with their environment, enhancing usability and safety by providing real-time information about objects near the sensor's range.
