This purpose of this project is to use two DS18B20 (Dallas) Temperature sensors one outside and one inside. The reason for two is to calculate to heat transfer from outside to inside the house. The house was built in the early 50's and has no insulation in the outside walls. A lot of heat is transferred through the walls in the summer and winter. So, the data collected from this project will be used to calculate both the inefficacy of my HVAC unit. However I am still working on getting the second sensor to collect data. I believe it's a code issue with the address scanner portion.
