I tested the SDI12_Mod.h solely and the microcontroller will restart after begin the library 🙁

Problem solved(7 Feb 2017)
I am now using hardware interrupts D10 (you need to cut the trace solder a jumper to D10 at SJ1 on the back of the board)
Now you don’t need the pin change interrupt library(conflict with SDI library)

Below is the code:

//Sleep mode setting 
#include <avr/sleep.h>

//RTC Setting
#include <Wire.h>
#include <Sodaq_DS3231.h>

char time_stamp[20];

void setup(){
  //Start Serial
  Serial.begin(57600);
  
  //Begin RTC
  Serial.println("Begin RTC");
  if (!rtc.begin()){
    Serial.println("Couldn't find RTC");}
  //rtc.setDateTime(DateTime(__DATE__, __TIME__));
   
  //Begin sleep mode 
  pinMode(10, INPUT_PULLUP);
  attachInterrupt(2, wakeISR, FALLING);

  rtc.enableInterrupts(EveryMinute);    //RTC interrupt mode
  set_sleep_mode(SLEEP_MODE_PWR_DOWN);  //Set the sleep mode  

  Serial.println("Setup completed!!!");

}

void loop() 
{
   
  Serial.print("logging at: ");  
  sprintf(time_stamp, "%02d:%02d:%02d",rtc.now().hour(),rtc.now().minute(),rtc.now().second());
  Serial.println(time_stamp); 
  
  //delay(10000);
  
  //Sleep
  systemSleep();
}


void wakeISR(){
  //Leave this blank
}


void systemSleep(){
 
  //Wait until the serial ports have finished transmitting
  Serial.flush();
  //Serial1.flush();
  
  //The next timed interrupt will not be sent until this is cleared
  rtc.clearINTStatus();
    
  //Disable ADC
  ADCSRA &= ~_BV(ADEN);
  
  //Sleep time
  noInterrupts();
  sleep_enable();
  interrupts();
  sleep_cpu(); 
  //wake up here 
  sleep_disable();
 
  //Enbale ADC
  ADCSRA |= _BV(ADEN);
  
}

//Sleep mode setting

#include <avr/sleep.h>

//RTC Setting

#include <Wire.h>

#include <Sodaq_DS3231.h>

char time_stamp[20];

void setup(){

//Start Serial

Serial.begin(57600);

//Begin RTC

Serial.println("Begin RTC");

if (!rtc.begin()){

Serial.println("Couldn't find RTC");}

//rtc.setDateTime(DateTime(__DATE__, __TIME__));

//Begin sleep mode

pinMode(10, INPUT_PULLUP);

attachInterrupt(2, wakeISR, FALLING);

rtc.enableInterrupts(EveryMinute); //RTC interrupt mode

set_sleep_mode(SLEEP_MODE_PWR_DOWN); //Set the sleep mode

Serial.println("Setup completed!!!");

}

void loop()

{

Serial.print("logging at: ");

sprintf(time_stamp, "%02d:%02d:%02d",rtc.now().hour(),rtc.now().minute(),rtc.now().second());

Serial.println(time_stamp);

//delay(10000);

//Sleep

systemSleep();

}

void wakeISR(){

//Leave this blank

}

void systemSleep(){

//Wait until the serial ports have finished transmitting

Serial.flush();

//Serial1.flush();

//The next timed interrupt will not be sent until this is cleared

rtc.clearINTStatus();

//Disable ADC

ADCSRA &= ~_BV(ADEN);

//Sleep time

noInterrupts();

sleep_enable();

interrupts();

sleep_cpu();

//wake up here

sleep_disable();

//Enbale ADC

ADCSRA |= _BV(ADEN);
