3. Results and Discussions
4. Conclusions
- ➣
- Arduino programming with an Arduino UNO interface board was used and recorded the temperatures with less effort.
- ➣
- No abnormality was observed during the experimentation in the temperature readings recorded by the program.
- ➣
- The solar radiation intensity followed by the ambient temperature affected the thermal performance of the desalination system significantly.
- ➣
- A drastic rise in yield was observed after 12 h every day, as the rate of condensation was higher after this time.
