This CMPS03 Magnetic Compass is now discontinued. We suggest other magnetic sensors as a great replacement. The Devantech CMPS03 Magnetic Compass Module is a top - notch tool to detect the rotation angle relative to the Earth's magnetic field. It offers a high resolution of 0.1 degree and an accuracy of about 3 to 4 degrees. You can easily connect it to microcontrollers like the BasicX or BasicATOM. With this module, you can precisely know your robot's orientation towards the North after calibration. This compass is specifically designed for robot navigation. Robots have many ways to measure distance, but few can determine orientation well. This magnetic compass is a perfect addition to your robot's navigation system. Specifications include a 5V voltage, a typical 20mA current, and it has a compact size of 32mm x 35mm. It has two types of outputs: a timing pulse and an I2C interface. You can access technical details at http://www.robot - electronics.co.uk/htm/cmps3tech.htm and also get Arduino sample code. The shipping list includes one CMPS03 Magnetic Compass.
Using the CMPS03 Magnetic Compass is easy. First, connect it to your microcontroller, like the BasicX or BasicATOM. After that, calibrate it to accurately determine the robot's orientation towards the North. When using, keep it away from strong magnetic fields as they can affect its accuracy. For maintenance, make sure to store it in a dry and clean place. Avoid dropping or applying excessive force to the module.
