Abstract

The equipment of automatic pH control system has been introduced on the hydroponic with microcontroller ATmega328p. The aim of this research is to create a pH control system to reins water pH on hydroponic. This control system consists of hardware such as pH sensor, microcontroller Atmega328p, servo motor, water pump, LCD and software such as program algorithm. Hardware components were control by program algorithm. The pH value of hydroponic was monitored by pH sensor. The pH value has been read by the sensor used to servo control on taps the acid and alkaline shelter. The pH control uses range of 5.50 to 6.50 as set point. The results showed that pH sensor has the calibration average error of 2.28%. The pH control system showed servo 2 ”ON” and servo 1 ”OFF” when pH value < 5.50. This resulted that addition of an alkaline that increasing pH of the liquid. And than servo 1 and servo 2 “OFF” when pH value on 5.50 to 6.50. This shows that the pH of the liquid on set point condition. While the servo 1 “on” and servo 2 “OFF” when pH value > 6.50 which resulted the addition of acid liquid that resulting decrease on pH of the liquid.
