Building Wireless Sensor Networks

  • Oops, I think I didn’t see your adapter link on this one. Yes, this should work.

  • Not this one. You should either choose a U.FL antenna or use one of the XBees with an RPSMA connector.

  • XBee’s are not designed or optimized for video, though they’re great for controlling a pan/tilt mechanism or another controller that’s attached to a webcam.

  • No absolute need for a separate XBee adapter, though it might be useful in configuring the XBee directly. Also if you’re trying to get your XBee on the Internet, then check out the XBee Internet Gateway

  • Digi’s XBee Examples site!

  • The book is intended to be a practical guide to creating wireless sensor networks using the ZigBee protocol. It’s written with hobbyists, students, makers, hardware hackers, designers, artists, and prototypers in mind. While there’s sufficient references to keep the adventurous beginner moving, there’s plenty of meat on the bone for those experienced with making things. For example, the first chapters aren’t about theories or circuits at all, they’re about what to buy and configure to get up and running quickly.

    Guessing from your question that the book would work well for you, so if you get it, let us know what you think.

  • The router is indeed doing the analog to digital conversion. The coordinator that’s receiving the messages from the router in this case needs to be in API mode because it has to generate API IO frames to deliver the structured data that came from the router radio.

  • You can also power-cycle the XBee to reset it, by gently lifting it out of the socket and replacing it.

  • Actually the Series 1 XBees are still fully supported and quite useful. They typically support basic 802.15.4 while the Series 2 typically supports ZigBee.
    See the Demystifying 802.15.4 and ZigBee white paper for more info. (registration optional)

  • It does not matter. The classes are independent so you could take both together or either one alone. The class design takes this into account. Basics are reviewed at the beginning of the second class to be sure everyone is on the same page. From there, the projects we do will be different from day one so things will stay interesting all the way through.
