Starting Sensor Networks with Arduino and Raspberry Pi teaches you ways to construct sensor networks with Arduino, Raspberry Pi, and XBee radio modules, or even indicates you the way to show your Raspberry Pi right into a MySQL database server to shop your sensor data!
First you'll know about the differing kinds of sensors and sensor networks, together with how you can construct an easy XBee community. Then you'll stroll via development an Arduino-based temperature sensor and knowledge collector, via construction a Raspberry Pi-based sensor node.
Next you'll examine alternative ways to shop sensor info, together with writing to an SD card, sending info to the cloud, and establishing a Raspberry Pi MySQL server to host your information. You even connect with and engage with a MySQL database server without delay from an Arduino! eventually you'll how one can positioned all of it jointly via connecting your Arduino sensor node on your new Raspberry Pi database server.
If you need to see how good Arduino and Raspberry Pi can get alongside, specially to create a sensor community, then starting Sensor Networks with Arduino and Raspberry Pi is simply the e-book you would like.

Look at the first message. It shows a data payload of 77 77, as you sent, but it also contains the 64-bit and 16-bit addresses of the sender. Compare that to your XBees and ensure that it is indeed the router (00 13 A2 00 04 8C CC AA / D8 B6). Now look at the message sent from the end device (not the broadcast). Can you find the sender’s address? Does it match your end device? It does! With these examples, you can see how to determine from where a data message was sent. If you were wondering how the mesh could automatically configure and heal itself and not lose what came from where, wonder no longer.

Sadly, it isn’t always obvious that that is the case. com/support/kbase/). There is a wealth of information out there. Chances are, someone has had a similar problem, and a simple search of the knowledgebase and forums may reveal the solution. Summary In this chapter, we covered a lot of ground. You were introduced to the XBee-ZB module and the ZigBee protocol, and you experimented with the AT and API firmware. You also learned a great deal about the XBee and its many features. Although it seems like I discussed a lot, the truth is that you have only just begun learning about the XBee and how to use it in your sensor networks.
