    Controlling water pH content on hydroponics growing media very required becouse water pH content generally tend to be alkaline. This situation doesn’t meet the water pH ideal. pH for growing media differ according for type of plants. Designed using microcontroller Arduino mega 2560 based PID method for compares the value of actual pH levels are read by pH sensor with value of setpoint (value of desired pH levels). Comparison of result method PID is converted into an action the pump of acid and base until the desired setpoint is reached. The control equipped with solar cell modules with capacity 20 wp to fill a battery with 12 volts of capacity as a energy source on appliance.
