Compass B Module is an easy-to-use, high precision electronic compass. Accessed via cmdBUS and BASIC Commander, Compass can be used to determine the current directional angle with respect to North and the magnetic field intensity. Because of the ease of calibration of the compass, it can be used for all kinds of applications.

Feature

• Directional angles with respect to North in unit of degrees.
• 3-axis magnetic field measurement.
• Special deviation angle function: Compass Module gives users directional angles with respect to certain directions, not limited to North.
• Deviation reminders: Compass B sends out reminders when the current direction is out of the preset directional angles.
• Automatic refresh of current directions: 5 refresh rates
• Activate calibration mode through software or hardware buttons at any time.
• Up to 256 angle storage memories: current angles, arbitrary angles as the base angles of the deviation angle function.
• High directional angle precision: up to degrees.
• Maximum detectable magnetic intensity up to ±300µT.
• A minimum resolution of 0.6µT in the x and y axes and 1.2 µT in the z axis.
• Up to 20 measurements per second.

Projects

Here are some ideas to help you get started with this module:

• Obtain digitized directional angle with respect to th north
• Combine with Innobot to navigate to a fixed position, like in a maze.
• Measure magnetic intensity of certain instrument and display the information on LCD
