(The Gist of Science Reporter) Proximity Sensor
This is able to detect the nearby objects without any physical contact
and is placed near the earpiece of the mobile. It consists of Infrared LED
and IR light detector. The IR LED emits invisible light and when the light
is reflected, the IR light detector detects the reflected light and the
system will know that there is an object nearby.
