Devantech CMPS03 Magnetic Compass

qty:

The CMPS03 from Devantech is an accurate magnetic compass, 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 Earth’s 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 the PicBasic Pro compiler.

Examples of using the CMPS03 module with a wide range of popular controllers may be found here.
