About Compass Sensor, Direction Finder Compass Android App

Compass is an instrument used for navigation and orientation that shows direction relative to the geographic cardinal directions. Usually, a diagram called a compass rose shows the directions north, south, east, and west.
There are electronic devices called magnetometers that act as compasses even though they are not using the "floating needle" approach to finding true north. Magnetometers measure the strength and direction of a magnetic field using electronic methods, and are so miniaturized as to be able to be placed in integrated circuits that are in the boards that drive cell phones. No need for GPS, they find north the way a regular compass does, and they point to magnetic north, not the North Pole, like regular compasses.

How it works goes as follows:
The magnetic needle inside of the compass uses the earth's magnetic field to point north. It is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west.
The north end of a compass magnet is drawn to align with the Earth's magnetic field. Because the Earth's magnetic North Pole attracts the "north" ends of other magnets, it is technically the "South Pole" of our planet's magnetic field.
Navigating in the Unknown
It is one thing to navigate from a position you are familiar with, but if you are in unknown territory you can use a method called triangulation. First, choose two distinct points of reference in your surroundings. For instance, identify a feature to the northeast and another to the southeast. Next, use your compass to record their directions in degrees from your position. Try to identify the two features on your map, and when you have done so, draw lines from the datum points corresponding to the angle from each position you have recorded. Identify your position by where the lines intersect.
Portability
One of the benefits of a compass is that it is portable. The slim and compact dimensions of most modern compasses enable you to add one to a pack of any size without worrying about additional weight. Most compasses can fit in your pocket. Some come with straps so you can hang them around your neck or wrist to keep from losing them.
Self-Sufficiency
When using a compass, you can establish your direction and position on your own. Even if you are alone in the wilderness and far away from a town or even a homestead, as long as you have a compass and an accurate map you can happily navigate across the environment without requiring the aid of another person and without needing an electrical power source.
Another benefit of using a compass is the rapidity with which you can take a reading. While a modern global positioning system, or GPS, can give a more accurate reading faster, you can still take out your compass, pinpoint your current position on a map, and establish your future trajectory in a matter of minutes. On the other hand, using a transit to establish your position can take between 10 and 15 minutes, and offers no real advantages in accuracy.
