Summary

In this chapter, you have put your Arduinos in control of your radio modules, and set up your very first wireless sensor network by wirelessly transmitting measured values to your coordinator node. By applying what you have learned, you can extend your network by adding more Arduinos with DHT sensors. You should even be able to add different kinds of sensors by adding a new packet type!

Now, reading your measurements in the serial console is nice, but not very convenient. In the next chapter, you will find out how to store all this collected data on your computer, or even directly in the cloud, and how to gain more insight by generating convenient graphs out of the data.
