Thanks a lot for your Help Rob, everything worked well and i am learning a lot 
At this point i need to incorporate this sensor as well,
http://www.smartec-sensors.com/assets/files/pdf/manuals/SMTH08INv2.2.pdf
How do i incorporate both sensors considering they use 3.3V & 5V I2C Systems ?
The datasheet is rather confusing to me, how do i read this sensor, do i need to initiate a "conversion" first ?
Some general help and or skeleton code would be appreciated.
Pete
