A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact. A proximity sensor often emits an electromagnetic or electrostatic field, or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal.
Nearly every Nokia smartphone nowadays comes with inbuilt proximity sensors. These sensors are used to turn the screen off when you answer the call to avoid accidental contact with the skin. But we have found some cool apps which make a better use of these sensors in day to day life.
