MG-300C MEMS north finder integrates high efficiency MEMS gyroscope and MEMS accelerometer in independent construction. The gyroscope and accelerometer chosen by the module signify the leading level of MEMS course of inertial system. the angular motion of the three-axis MEMS gyroscope delicate provider, the linear acceleration of the three-axis MEMS accelerometer sensitive service, the bias of the complete temperature parameters, the scaling factor, the non-orthogonal error and the compensation of the acceleration-related gadgets are carried out contained in the module, and the measurement accuracy may be maintained for a long time. At the same time, the module adopts integral vibration reduction, sealing design and other measures to ensure that the product can accurately measure the angular motion and line movement parameters of the service in harsh environment, thus providing customers with low value and high reliability options.
The Earth’s diameter is about 8,000 miles (12,875 kilometers), which is a great distance for the planet’s magnetic field to go before affecting your compass. That is why a compass has a lightweight magnet and a frictionless bearing — otherwise, there simply is not sufficient power within the Earth’s magnetic area to turn the needle.
You will need to first determine what your drift IS, through testing and your trusty LCD display (or RobotC debugger window). Line up your robotic again to the corner of some area tiles & turn it on. Let it sit to orient itself; the LCD should read 0 (it will assist if you have it display degreesTurned, except you want thinking in phrases or uncooked sensor output).
