there are different types of proximity sensors namely inductive capacitance and infrared. the working principle of inductive proximity sensor is,
it consists coil, oscillator, detector and trigger circuit. when current flows through a coil magnetic field will be generated and when the metal get contact with that field
the voltage is induced in the metal the detector detects this loss in voltage and triggering circuit will give the contact output...

∙ 7y agoA proximity sensor reduces the volume from the earpiece/speaker on the handset, when it's held close to your body. It's designed to stop you damaging your hearing by having the volume on ringtones and/or music set too high.

What is working principle?
A working principle is a regulation or rule that is used so that work can be done. This is a general phrase that can be used in any circumstance from the working principle of a motor, to the working principle of a solar cells.

What is difference between photoelectric sensor and proximity sensor?
photoelectric sensor-sense both metal & non-metal proximity sensor -sense metal only
What is the working principle of infrared proximity sensor?
If it's PIR (that's passive infra-red) then think of it as an eye that can only see changes in heat, staring straight forward. Whenever something that's warmer or colder than the background moves in or out of its field-of-vision, the sensor reacts to this change in scenery and trips an alarm.
What is the difference between magnetic pick up and proximity sensor?
A limit switch turns on or off when the object being sensed reaches a specific location.A proximity sensor returns an analog signal indicating how far the object is from the sensor.
What is proximity sensor on android ascend 2?
Proximity sensor allows the Mobile display to off during call when mobile is near to ears.
Who invented the first proximity sensor?

What is a proximity sensor used for?
A proximity sensor is used for detecting close objects by emitting an electromagnetic field. These are useful for detecting objects without touching them.

Can a mobile work without the proximity sensor?
Yes it can. The proximity sensor is only used to reduce the volume when you hold it to your ear. You should be able to set the volume level manually.
What sensor do you use to detect a moving target crossing a certain point?
Infrared proximity sensor.
