Hello, world.

Andrew here, JavaScript developer and electronics enthusiast.

In this workshop we're going to talk about the Internet of Things with JavaScript.

Firstly, what is the Internet of Things or IoT?

The Internet of Things is described as physical objects that have embedded

sensors, software, and electronics that are connected to the Internet.

Data is collected by or sent to the devices.

Internet of Things devices can connect to the Internet in a couple of ways.

Directly via WiFi or Ethernet connected to a router, or

IoT devices can connect through a gateway device like a smartphone via Bluetooth.

There are other wireless technologies too, like Zigbee and Z-Wave,

where devices connect to so-called hubs,

that in turn connect to your phone or Internet services.

Let's take a look at some examples of IoT devices.

There's the Nest thermostat that can be controlled remotely via an app.

The Nest can also automatically adapt and

program itself depending on your habits and as they change throughout the year.

Samsung produced a line of security cameras that can connect to the Internet,

so you can see what's happening when you're away from home or your office.

It also allows you to speak to intruders, relatives and

friends through a built-in speaker.

There are a number of smart lock solutions on the market, which make it easy for

you to lock and unlock your doors.

Smart locks allow you to check your doors and lock them even when you're miles away.

We all can get forgetful when we're rushed.

AirBNB hosts often use smart locks to give guests digital keys that allow

them to access their property for short amounts of time through their smartphone.

IoT is being used in the medical industry too, for

example, with smart glucose monitors.

All your blood sugar history is stored online and can be shared with your

physician, allowing more personalized and real time care.

Fitness is another area that's seen growth in IoT products.

Fitbit uses sensors to collect information on activity, and

then connects to your smartphone to send that information back to the Internet.

Not only does it help you keep track of your activity, but

you can also work on your goals with your friends too, through social features.

Have been creating smart mirrors that display calendar and

weather information, amongst other things.

This can be handy to remind you to take your umbrella

on the way out if it's going to rain later.

Retail stores can install smart signs that can be updated in real time.

This is great for AB testing sales in physical locations.

Amazon has a number of smart devices, like their Dash button.

These buttons connect to your Amazon account, and

reorders commonly used products.

This technology is being built into devices like coffee makers and

washing machines.

Lighting is another area that is being connected to the Internet.

Imagine being away from your home longer than you expected.

With Internet connected lighting,

you can switch on your bulbs when you're away to look like you're home.

With the combination of big data and

IoT, farmers are able to use algorithms to generate better crop yields.

The automotive industry are making you safer

by alerting emergency services if you're in an accident.

Climate researchers can deploy cheap,

inexpensive sensors to get approximate readings over vast distances.

If any of their weather stations report back interesting or

peculiar readings, they can go out and get more detailed readings.

Both commercial and consumer electric meters can help you monitor energy

consumption and give you suggestions on how to save electricity and money.

On production lines, sensors can be triggered when things go wrong.

If they're connected to the Internet, they can alert who needs to know immediately,

so that they can come and fix the issues.

In the next videos, we'll start looking at the solutions available for

JavaScript and the Internet of Things.
