Time temp moisture

this arduino sketch will run all three sensors:

/*

david thornton 2015 01 22
this script does three things
1. get time from DS3231 RTC
2. gets temp + humidity from HTU21D
3. gets soil moisture from 

TAKEN from DS3231_SIMPLE


DS3231_test.pde

4/11
Test/demo of read routines for a DS3231 RTC.
Turn on the serial monitor after loading this to check if things are
working as they should.
