Proximity Sensor

Proximity, a world that captivated me after a discussion with a friend.

prox·im·i·ty [prɒkˈsɪmɪtɪ] 

Etymology
From Middle French proximité, from Latin proximitās, proximitāt-, from proximus.

Noun
proximity (plural proximities)
- closeness; the state of being near as in space, time, or relationship.
- the state, quality, sense, or fact of being near or next.

And for this time being, i think i would consider myself to be in a need for a proximity sensor.

Proximity sensor
From Wikipedia, the free encyclopedia 

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 field or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal. The object being sensed is often referred to as the proximity sensor's target. Different proximity sensor targets demand different sensors. For example, a capacitive photoelectric sensor might be suitable for a plastic target; an inductive proximity sensor always requires a metal target.

The maximum distance that this sensor can detect is defined "nominal range". Some sensors have adjustments of the nominal range or means to report a graduated detection distance.

Proximity sensors can have a high reliability and long functional life because of the absence of mechanical parts and lack of physical contact between sensor and the sensed object.

Proximity sensors are also used in machine vibration monitoring to measure the variation in distance between a shaft and its support bearing. This is common in large steam turbines, compressors, and motors that use sleeve-type bearings.

International Electrotechnical Commission (IEC) 60947-5-2 defines the technical details of proximity sensors.


A proximity sensor adjusted to a very short range is often used as a touch switch.


So, after reading all of those explanation.
I come to a conclusion we all need to activate our own proximity sensor more.

Let me explain it to you, and by nearby objects i mean love.
Each one of us have this sensor but are we using it in the right way?
When you meet someone, do you feel the electromagnetic field around you, a tingle in your heart, butterfly in tummies, and you will always look for a return signal.
And each one of us, even if we all look for the same object (love), but we must have different "targets", and also different "sensors".
Our "maximum distance" and "nominal range" is also different, some just know in an instant, some other need more time to get to know the "targets" before the "sensors" can work.

And this is the real deal, and the most important thing to be noted:
Our proximity sensors should also have a high reliability and long functional life when there is an absence of "mechanical parts" (if you know what i mean) and lack of physical contact between "sensor" and the sensed "object" (of affection) or in our case could also be the "targets".
Because in my opinion, sometimes the physical contact affect and maybe wreck our sensors and cause us to mislead into something that is not our main object (love).
