PurIrriGrow: An Automatic Desalination and Irrigation System is an innovation developed to address freshwater scarcity in the agricultural sector. The system utilized a parabolic trough and solar still to thermally desalinate the saline water, while an Arduino Uno R3 and different sensors were used to automate the irrigation. The researchers conducted six experimental tests to examine the functionality of the PurIrriGrow. Two of the tests were conducted to assess the thermal desalination components by circulating water through the system. The two tests proved that the overflow system and solar still performed their intended functions. The remaining four tests were conducted to assess the automatic irrigation components. The meter for water quality, ultrasonic sensor, soil moisture indicator, and LCD screen all proved to respond to their triggers without noticeable time delays. The results of these experimental procedures indicate the potential of PurIrriGrow in freshwater production and automated irrigation.
