Özet
This paper presents a simple, low-cost liquid based optical tilt sensor. The sensor is designed on the basis of the variation of the amount of light passing through liquids composed of two layers placed in a container depending on the tilt angle. Light is transmitted and received by the fibers placed in the container ends. This sensor is highly sensitive to small angle values, especially depending on the fiber radius used. An average of 0.58 V/° sensitivity was obtained in the range of 0-3° by using 2.5 mm diameter fibers. This value is found to be 4.54 times higher than the sensitivity of sensor with single liquid.
