The CC3000 WiFi chip from Texas Instrument is a quite versatile chip that can be used to connect your projects to the web. However, connecting your Arduino project to a web server can be tricky: you need to know how to install & configure a web server, and know a bit about HTML & PHP. Luckily, there are other solutions to make things easier.
In this guide, we are going to see how to connect a temperature & humidity sensor to an online platform for connected objects, Xively. The sensor will be connected to an Arduino Uno board, which will also communicate with the Adafruit CC3000 breakout board for the WiFi connectivity. But instead of communicating with a local server, the CC3000 chip will communicate directly with the Xively server and send the data over there. At the end, you will be able to monitor the data sent by the server directly from your browser, wherever you are in the world, just by logging into the Xively website.
