Using PH storage solution this probe - for how long can be stored before initial interfacing and the actual use of the probe after whole project done

I would say up to a year is safe. You may want to shock it with 10% acidic solution as a cleaner after a year.

Does this sensor array plug directly into arduino? Do you have link for code to set up parameters?

This unit has 2 cables... One cable for 12vdc power. The other cable has the outputs you plug directly on Arduino analog inputs and grounds. I will paste it here /* 1.00 2014-05-22 PP -Created -------------------------------------------- This sketch is used to read the PH and EC values from the A1005 transmitter. */ //Define and set constants #define EC_PIN_NUM 1 #define PH_PIN_NUM 2 #define EC_LED 3 #define PH_LED 4 int ecPin = A1; //The analog input pin used by the EC sensor int phPin = A2; //Thw analog input pin used by the PH sensor //Variables to store the processed values float finalPhValue = 0; float finalEcValue = 0; //Define variables used in methods here int rawPhReading = 0, rawEcReading = 0; int processedEcValue = 0, processedPhValue = 0; void setup() { Serial.begin(9600); } void loop() { ProcessPH(true); ProcessEC(true); Serial.println("---------------------------"); delay(1000); } void ProcessPH(bool printToConsole) { rawPhReading = analogRead(PH_PIN_NUM); processedPhValue = map(rawPhReading, 0.00, 1023, 0, 14.00); finalPhValue = rawPhReading*14.00/1024; analogWrite(PH_LED, processedPhValue); if (printToConsole) { Serial.print("PH > "); PrintParamsToConsole(rawPhReading, processedPhValue, finalPhValue); } } void ProcessEC(bool printToConsole) { rawEcReading = analogRead(EC_PIN_NUM); processedEcValue = map(rawEcReading, 0, 1023, 0, 3200); finalEcValue = rawEcReading*3200.00 /1024; //Readible EC finalEcValue = finalEcValue / 1.00; analogWrite(EC_LED, processedEcValue); if (printToConsole) { Serial.print("EC > "); PrintParamsToConsole(rawEcReading, processedEcValue, finalEcValue); } } void PrintParamsToConsole(int rawReading, int processedValue, float finalCalculation) { Serial.print(""); Serial.print(""); Serial.print(finalCalculation); Serial.println(" "); }

If i store this for a year after initial test because my software is under development. using kcl +di solution i brought from amazon will it be ok?

yes, you may store with kcl solution. It does come with a protective plastic cap that does have kcl in it.
