Abstract

Detection of Rhodamine B levels in distilled water based on displacement sensor can be done using fiber coupler and concave mirrors as reflector. The mechanism of detection is done through changes in the value of the voltage peaks due to absorption of Rhodamine B solution against the green light with a wavelength of 532 nm. This sensor system capable of detecting Rhodamine B levels in distilled water with a range of 0 – 8 ppm and a resolution of 0.02 ppm..
