I am new to arduino. I am trying to build a simple water quality arduino based sensor. I have Arduino UNO R3 at the moment. The goal is to build a arduino sensor platform which can store data (may be SD card) and a wifi functionality so that I can store the data and as well as transfer the data into a webpage for remote application. I was wondering what is the best shield option can chose to get this done. I can see a wifi shield and a data storage shield, but is there is way I can get this done with one shield?
What other circuitry will be needed for the sensors ? Perhaps a shield type arrangement is not the best.
