A two dimensional digital clinometer with dual axis micromachined accelerometers

2측 MEMS 가솔도 센서를 이용한 2차원 디지털 경사계

This paper deals with a new two dimensional clinometer based on dual axis micromachined accelerometers. The clinometer is a small and low-cost product, which is mainly developed to help golfers read easily the tilt of a putting green. First, this paper proposes the principle of two dimensional clinometer and also a calibration method to improve accuracy with respect to the offset voltage and sensitivity of a accelerometer. Experimental results show that the proposed clinometer can provide useful information on the tilt of an inclined plane.
