Let's summarize what we did in this project. We built a simple and cheap Wi-Fi temperature sensor based on the ESP8266 chip. We configured it to automatically log data on the Dweet.io service, and we displayed these measurements inside an online dashboard.

There are many ways to improve this project. You can simply add more sensors to the project, and display these measurements as well inside the Freeboard.io dashboard.

You can also, for example, completely change the project, by connecting a motion sensor to the ESP8266 board. You can then configure this sensor to automatically send you an alert when motion is detected, for example via e-mail or using Twitter. The possibilities are endless!

In the next chapter, we are going to see how to do another important thing in any IoT project: controlling devices from the cloud.
