Detection of Arsenic Contamination in Drinking Water using Color Sensor

Arsenic is one kind of chemical element that can poison surface water with causing many human difficulties. For detecting and giving a clear view of arsenic contamination in water there are different types of researches going on. Most of the researches are developed for laboratory work. In this work, not only a system was developed but also a simple theory was described that will detect the arsenic percentage of water easily. Modern arsenic detecting kit and simple color sensor have been used for developing the system. Some sample of water was collected from different region of Khulna, Bangladesh to measure the percentage of arsenic contamination. The data was recorded and analyzed to verify the system.
