Water quality is essential for public health, environmental protection, and industrial processes. Dissolved organic compounds, even at trace levels, can significantly affect ecosystems and human safety. Many organic molecules, including simple hydrocarbons like Ethene and carbonyl-containing compounds like Ethanal, absorb strongly in the ultraviolet (UV) spectral range. This absorption arises from electronic transitions in π-bonds and carbonyl groups. Measuring UV absorption provides a sensitive, non-invasive method to detect organic contaminants in water.
Traditional monitoring approaches rely on laboratory-based chemical analysis. While accurate, these methods require sample collection, transport, and processing, limiting temporal resolution and responsiveness. By contrast, optical techniques allow real-time, in situ monitoring, providing continuous information about water quality without extensive sample handling.
The proposed project focuses on a UV-laser-based absorption sensor using a Silicon Photomultiplier. A UV laser transmits light through the water, and the SiPM measures the transmitted intensity. Silicon photomultipliers are compact, robust, and highly sensitive, capable of detecting small variations in light intensity. The attenuation of the laser beam follows the Beer–Lambert law
