# WiFi Weather Station ## Introduction ![](https://cdn-learn.adafruit.com/assets/assets/000/021/410/medium800/projects_Screen_Shot_2014-11-25_at_10.35.24.png?1416909635) As open-source hardware users and makers, we love playing with new chips, boards and tools. And there is one chip which is quite popular these days: the CC3000 WiFi chip from TI. This all-in-one module has low-power WiFi and a microcontroller-friendly interface. It has been featured in many articles around the web, and the Adafruit's CC3000 breakout board really makes it easy to integrate this module in any Arduino project. In this tutorial, you will learn how to use this chip for home automation purposes. And in particular, we are going to see how to use this chip to build a simple WiFi-connected weather station. The station will measure two variables: temperature and humidity. But we won’t display the information on an LCD screen, like a weather station you could buy in a store. No, instead, we will transmit the data wirelessly via WiFi to your computer and display it there on a nice interface. Excited? Let’s get started!
