Use of TCS3200 sensor to identify heavy metal materials

Abstract

v> Heavy metals are natural components that are toxic and can endanger living things even in a very small concentration. Water that is polluted by heavy metals in a certain concentration can harm the ecosystem and can be fatal if entered the human organ system. The principle of heavy metal concentration measurement using the TCS3200 sensor is a sensor will sense the color gradation from dissolved heavy metal. This color gradation will be calibrated to a concentration of dissolved heavy metals. Heavy metal material that is used for this research were FeCl3, NiSO4, and CuSO4. Based on the analysis results, there were 4 results obtained. The first one was performance specification from this instrument consists of a TCS3200 sensor, black acrylic box for the sensor placement. In the black acrylic box, there was a hole sample for sample placement. The second result was the effect of changing in heavy metal concentration to sensors output data is proportional. The third result was an instrument calibrating with existing data. The fourth result was accuracy and precision from the instrument which have been calibrated. For FeCl3 material, the average accuracy was 95.5% and precision was 98.7%. For NiSO4, the average accuracy was 96% and precision was 98.3%. For CuSO4 material, the average accuracy was 99.7% and precision was 99.8%.
