4/5/11-Day Twenty-five

Today was a big day for Awe and I in Green Tech. We began class by just reviewing the information on elab.hpa.edu while Dr. Bill was going around talking to individuals about their projects. Then, when Dr. Bill got to our project, we went over how the sensors worked. We started out by just talking about the cottages. Awe and I are also going to be keeping track of all six cottages and we are going to make some kind of directory page that contains certain information about each cottage. We also went over how CO2 is going to start to become a big deal because people get taxed on the CO2 produced while making the energy to power their house or business. We also talked about how TED sensors are going to be put around the school so we record the energy history, and make changes. They are already set up around the energy lab. Two sensors that we talked about are the TED Solar for the energy lab, recorded on IP address 10.14.64.2, and the TED sensor for the energy lab use recorded on 10.14.64.4. When we visited these IP addresses, we noticed that neither sensor was currently reading any activity, so that's when Dr. Bill decided to take us down and show us how everything worked, and how the sensors talked to each other.



NOTES:

•Energy lab has 3 phase wires (picture on the right)
•Blue wire-White wire: 110volts
-Middle wire: 220volts

•Normal house--has 3 wires
1. 120volts
2. 0volts
3. -120(?) volts
-Main energy suckers are the dryer, stove, water heater, oven, and anything that generates a lot of heat

•TED SENSORS-->makes clamps, records history, makes it possible to change energy use
-sensors talk to each other, and check up on each other
–clamps-->wire--->converter (box)--->recordings/measurements
•CLAMPS:
-has lots of iron
-everytime a current goes through clamp and changes direction it creates a magnetic field.
-more magnetic force=more energy
-0-5volt signal (clamps put out 5v when receives 60 Amps)

•P=V*I
Power(watts)=volts*Amps
Volts=Pressure
Amps=Flow
