We’ve designed a photoelectric sensor to detect the concentration of SO42- solution with a vertical capsule which was immersed into sample solution derectly. The system contains a pair of light-emitting diode (LED) and photosensitive diode (PIN) packaged with cover of semi-sphere shape. Theoretical analysis and experimental results have shown that the relative transmission rate of the system was almost proportional to the concentration of solution; which meant that the more concentrated the solution was, the less the relative transmission rate would be. In our experiments, the concentration of SO42- solution can be detected within the range of 0-3.441mol/L by using a LED with a central wavelength of 940nm. We have also confirmed that the concentration of Zn2+ ( 3.441 mol/L), Cu2+ ( 0.5627 mol/L) and H+ ( 2.015 mol/L) had tiny effects on the detection results of SO42- concentration.
