Full text not available from this repository.Abstract
A new low-cost clean water sensor based on photovoltaic solar cells has been developed for addressing one of the problems related to the low reliability of solar water technologies in developing countries: the lack of sensors detecting when the water is safe to drink. The new design is capable of measuring the main parameters that are relevant to solar disinfection: global irradiance, sunshine duration, UV irradiance and water temperature. One of the key aspects of the design is the UV irradiance measurement. Two identical cells were used, one of them with a low-cost UV-blocking filter on top, so the total UV irradiance could be calculated as the difference between the two solar cells output. The first cell would be measuring UV-VIS-NIR and the second only VIS-NIR. The UV filter material was explored and a low-cost architectural film was selected. Initial materials costs for the first prototype was of approximately 4r, excluding labour.
