- Abstract
This article contains the description of MEMS accelerometers implementation to device which is able to measure danger tilt. We can find out actual tilt in two basic axes X and Y from -90° to +90°. Z Axis can only detect fall of device or in vehicle system very fast downhill grade during movement. For testing of the solution we select small mobile robotic carriage. Hardware and software part of solution are described. Because data from sensor are in raw format from analog MEMS Accelerometer, we use free C# library with Kalman Filter implementation to remove signal error. We can acquire next information from sensor data for example movement's trajectory in X/Y axis (Cartesian system) and actual speed in all three axes. Fast alarm is provided by RGB led diode (red color is dangerous tilt.
