Perancangan Sensor Gyroscope dan Accelerometer Untuk Menentukan Sudut dan Jarak

Abstract

Currently, determining the exact position and orientation in a technical system has an important role, especially in terms of control on a navigation system. Of the instruments used in navigation systems is the Inertial Measurement Unit (IMU). The IMU consists of a combination of the acceleration sensor (accelerometer) and the angular sensor (gyroscope) to track the whereabouts and movement of an object. In this final step is to design and manufacture of gyroscope and accelerometer sensors to determine angles and distances based on ATmega32 microcontroller to detect the rotation angle and position of objects. The data is obtained from the integral point of the gyroscope output signal in the form of angular velocity and accelerometer output in the form of the acceleration signal. Data from both these sensors are then displayed via computer with the program through a wireless RF c # YS-1020UA. Based on the results of research conducted on all three axis gyroscope axis to clockwise rotation angle value obtained with the smallest error in the roll axis of 0.55 % and for anti-clockwise rotation angle value obtained with the smallest error in the yaw axis of 0.39 %. The result of the best distance with the smallest error is on the y axis with an error of 1.37 %. Kata kunci : gyroscope,accelerometer, mikrokontroler ATmega3, YS – 1020UA
