Abstract

Solar stills use the sun's energy to distinguish between dirty and clean water. By utilising the thermoelectric effect, which can convert different temperatures directly into electric voltage or vice versa using a thermoelectric module, is one of the components to build this solar still. Conventional solar stills have drawbacks because there are too many distinct varieties, too many of them lack monitoring systems, and they rely on the sun's heat and the air's humidity to collect clean water. By including a thermoelectric system, evaluating the water's temperature and cleanliness, and developing a real-time monitoring system, this project hopes to increase the solar still's effectiveness. The solar still's top cover may be archived by using hemispherical top cover. The solar still will be placed along with the microprocessor Arduino Uno, PH sensor, and Water level sensor in order to monitor the quantity and quality of the distilled water. The heating plate will be used to control the temperature within the hemispherical solar stills to make the evaporation process more effective. Based on this thesis, it can be concluded that Hemispherical Solar Still + River Rock + Peltier has the best efficiency which is among the other test conducted in order to find the best possible modification for the solar to enhance the solar still performance which manage to collect 108 ml of safe pH level water which is at 7.25 ph value.
