CMPS03 Magnetic Compass
|
|
 |
The CMPS03 Magnetic Compass has been specifically designed
for use in robots as an aid to navigation. The compass uses
the Philips KMZ51 magnetic field sensor, which is sensitive
enough to detect the Earths magnetic field. The output from
two of them mounted at right angles to each other is used
to compute the direction of the horizontal component of
the Earths magnetic field. The bearing may be retrieved
from the module in one of two ways; either using its PWM
signal or its I2C interface.
An I2C interface is available on many popular microcontrollers
such as the
BASIC
Stamp BS2P and may be easily implemented on most PIC
microcontrollers using either the
PicBasic or
PicBasic Pro
compiler.
Examples of using the CMPS03 module with a wide range
of popular controllers may be found
here.
