In this chapter, we built a project that can just be put in a room to spy on it from anywhere in the world. It continuously records data from the sensors connected to it, and sends this data directly to the cloud.

There are of course many things you can do to improve this project. You can, for example, experiment with your own sensors, depending on the data you want to spy on. You can also try to replace the CC3000 Wi-Fi chip with the GSM/GPRS shield we used in an earlier chapter to have a module you can place somewhere without having to connect it to a Wi-Fi network.

In the next chapter, we'll dive into a more advanced topic: actually building a GPS tracker based on Arduino!
