Comparative analysis of the measurement methods for the wire´s position using the TSL1410R optical sensor

In the dams monitoring procedure there are several important aspects that must be taken into consideration when the specialists must give a detail report regarding the construction behavior during the operation. One of the above physical phenomena that must be followed is the inclination of the concrete blocks during the freezing / unfreezing intervals or maximal / minimal loads (from the lake´s water volume perspective) periods. That can be made using a dedicated sensor, a linear optical sensor with a large number of pixels that basically calculates the position of a wire, by its shadow position, by projecting it on the optical sensor using an area of powerful LEDs. The paper wants to identify the best method for the wire´s position determination using the TSL1410R optical sensor from two points of view: the speed of the wire´s position determination and the stability of the obtained results.
