A well designed and fabricated solar-powered hydroponic system that automatically regulates the pH of the pool. To test the ability of the Arduino-based microcontroller, the pH of the reservoir or solution can be pre-set to a certain value more or less than the value of equilibrium ( 7 x 8 ) which is read by the pH sensor for the system to work. The pre-set pH solutions are regulated by the two peristaltic pumps from two separate reservoirs (contains pH- Up or pH-Down ) incrementally. The amount of solution that is added to regulate the pH of the pool can be controlled depending on the amount that is encoded to the Arduino motherboard.
