Mike explores some of the latest and greatest networking technologies with the Internet of Things (IoT). He describes the three common wireless technologies used to connect to IoT devices, 802.11, Zigbee, and Z-wave. Mike finishes with a discussion and demonstration of typical IoT setups and configurations.
- How many different technologies does it take to turn on a light bulb? Well, the answer is three. So in this episode, what I want to do is talk about the Internet of Things, and I'm going to be concentrating on home automation because that's where we tend to see this type of stuff. Today when we say Internet of Things, we're talking about giving internet capability to all kinds of stuff that we would never have considered to be internet-capable before. Thermostats, light bulbs, refrigerators, hot water heaters, door locks, garage door openers, the list goes on and on of our ability to remotely control all kinds of devices simply by putting them on the internet. Ergo, Internet of Things. This little light bulb in my hand has a microprocessor, it has an address so it can be talked to, it has a API so I can make it do all kinds of stuff, change colors, things like that. I've got two light bulbs behind me. The one on the left is a monochrome light bulb, so it's just white, but this one will change into any color of the rainbow. I'll show you these guys in just a minute. But first of all, let's talk about the three types of technologies we use to talk to all of these devices. Now clearly, they need to be wireless and almost all Internet of Things devices are wireless. So first of all, 802.11 is going to be a very common methodology to talk to these kinds of guys. Second is Zigbee. Zigbee is used exclusively for Internet of Things. It's designed for home automation more than anything else. It's been around for a while. Zigbee runs on the 2.4 gigahertz band. It doesn't have a lot of bandwidth 'cause it doesn't need it. It's not like we're sending movies to our dryers. We're just trying to tell the dryer to turn on or turn off so there's not a whole lot of bandwidth necessary. The last one is called Z-Wave. Z-Wave runs in the 900 megahertz band, so it's a much lower band. Used to be used for different types of portable phones, but now it's a pretty quite band area, and we'll see that used a lot as well. Now the trick to Internet of Things is that you're first of all going to have to have some kind of hub, and that's what I've got here in front of me, so one of these is a Philips branded hub, which was designed to talk to, well, Philips light bulbs, but it will actually talk to all kinds of stuff, and then next to me is a classic Google Home. Okay, Google, what time is it? - [Digital Voice] It's 9:08. - So these little devices act as the primary hub for all of our many Internet of Things that we'll see in our homes. Now it will take some configuration. For example, I can use my tablet here and actually bring up an application. Now this application has two different lamps on here, so here's my white lamp, so I'm going to click on this. Hey, my lamp's on. You watch the lamp, I'm going to turn it off now. Cool, huh? Look at me (laughs) using all this technology to turn on a light bulb. And it's also got a dimmer on it as well. Now using tools like this are great, but what really makes a lot of these home automation tools even more fun is when we bring in voice tools. Like for example, you ready? Hey, Siri, turn all the studio lights green. - [Siri] (beeps) Okay, green. - How cool is that? So the answer is it takes three different types of technologies to turn on a light bulb. (mellow music)
