We report a vertical-pendulum-based fiber Bragg grating tilt sensor, which can detect the magnitude as well as the direction of the inclination from the horizontal direction. The sensor is insensitive to temperature, and preliminary results show that tilt angle accuracy and resolution of better than 0.1° and 0.007° can be easily achieved.
