Urgency of the research. Robots and vehicles which locomote on high slope ground has tendency to overturning and they lost stability during the locomotion. The problem also occurs in area of automotive industry. Target setting. All vehicles moving on the rough and inclined ground has a problem with stability. Emergency system for warning before dangerous tilt angle can be mounted inside the vehicles and robots as prevention of side overturning. Actual scientific researches and issues analysis. The problem is to find the reliable sensor for detection of dangerous tilt angle. Task is to identify the sensor properties as sensitivity, zero shift and also uncertainty of measurement. Before usingit is necessary to identify sensor properties. Uninvestigated parts of general matters defining. The questions of the filtering of data acquisition by tilt angle sensorare uninvestigated, because the next research will be focused to this topic.The research objective. Sine bar is used for verification and testing of tilt sensor. Sine bar angle is adjusted using the parallel length gauge blocks. Sensor reacts to the changed tilt angle proportionally with pulse width on output pulse widthsignal. Indication of sensed data is made via using the microcontroller and LCD display. Also all calculations are executed inside the microcontroller. The statement of basic materials. The tilt sensor can be mounted inside the problematic vehicles to detect dangerous tilt angle and also automatic system for change the center of gravity position can be designed. The system will compensate the dangerous tilt angle. Conclusions. Evaluated uncertainties are related to overall sensing system and not only for sensor. Only sensor alone cannot be tested, because the sensor has no indication module. Expanded uncertainty of the system for measurement of tilt has been obtained and it is value should be taken into account before the sensor using.
