Abstract

A luminescence based water quality sensor system (10) comprises a dual sensor material (300) having at least one layer of two indicator sensor dyes that display two largely different decay times in a single hydrogel matrix, in which each indicator sensor dyes measures a specific analyte relating to water quality, a light source (100) which provides photon source to the dual sensor material (300), an excitation source (200) which includes a polarization controller (201) to modulate and polarize the light source (100), and a detector unit (400) having a spectral filter (401) to filter the emission wavelength before detecting by a photodetector (402). The changes of the analyte to be measured quenches the luminescence emission of a sensor dye by determining the decay time of a reference indicator by measurement of the phase shift of the detected emission signal at two different modulation frequencies for a real- time and simultaneous calculation of the concentration of at least two analytes to be measured.
