/**
* Revision
* version 1.0
* ....
* version 2.5 02-14-2018: 3rd relay and remote time setting are added
* version 2.6 02-14-2018: DO Sensor added, calibration is still on the way
* version 2.6.3 02-19-2018: developing calibration. the average voltage is ok
* version 2.6.5 02-21-2018: developing calibration. Sensor read is completely ok
* version 2.6.8 02-27-2018: developing DO calibration. DS18B20 temperature sensor is added
* version 2.7 03-04-2018: DO calibration complete. IWDG is added
* version 2.7.5 03-08-2018: DS18B20 & IWDG is being developed
* version 2.7.5a 03-08-2018: DS18B20 problem discovered at line 42th ReadSensor.cpp
Upload RTC time converted to epoch
* version 2.8 03-18-2018: DS18B20 problem solved
* version 2.8.5 03-19-2018: Set time to turn on/off the relay
* version 2.9 03-22-2018: Watchdog worked. Some hardware bugs found
* version 2.9.7 03-29-2018: Try to upload 1 more time if upload fail
* version 2.9.7 03-30-2018
