No, the one that I have is not the Adafrruit one, I just could not find the one I had in the fritzing parts. Here is the barometric sensor that I bought: Amazon.com
That bmp.getEvent(&event); is the exact line of code that stops the webpage from even loading.
The temperature sensor that looks like a transistor on the breadboard, yes, is a TMP36. It closely parallels the temperature reading of the temperature probe, but maybe I will look into getting a DS18B20 as a better replacement.
The water temperature probe that I have already has a header on it to change from pullup or pulldown resistor. It communicates over the OneWire and DallasTemperature library.
I will change the resistor and wiring for the DHT sensor. I will use 4.7K to 5V.
I haven't had a problem with the flow sensors yet...but if I do I will try to find I2C versions.
Thank you for catching my mistake on the LED. DOH! I have a 470R with my led on my actual breadboard.
I am sorry I just realized that I posted my old version of the code before. My mistake. Here is the code that is the most updated:

It does not have any of the barometric stuff in it yet.
I have attached an image of the verbose output after I uploaded the code to the Uno. It is named Verbose Output.png. I have also added an updated image of my wiring diagram.
