Hi there, welcome back to this course.

2
00:00:05,340 --> 00:00:09,510
Let's start this lesson by defining the Internet of Things.

3
00:00:10,540 --> 00:00:19,660
Internet of Things refers to computing devices that are Web enabled and have the capabilities of sensing,

4
00:00:19,990 --> 00:00:29,260
collecting and sending data, using sensors and communication hardware and processors that are embedded

5
00:00:29,470 --> 00:00:31,000
within the devices.

6
00:00:31,780 --> 00:00:36,970
The slide shows the definition of IoT that Wikipedia provides.

7
00:00:39,950 --> 00:00:48,050
Let's now see what are the typical application areas of Internet of Things devices, the typical areas

8
00:00:48,050 --> 00:00:56,700
in which Iot devices and systems are used, range from industry to healthcare to automation.

9
00:00:57,050 --> 00:01:04,550
For example, let's think about devices for managing  home heating, lighting or entertainment.

10
00:01:06,560 --> 00:01:15,800
Other areas of use of Iot devices are the word of wearable devices and the vast world of city automation

11
00:01:16,550 --> 00:01:24,050
think, for example, of systems for the intelligent management of waste or parking lots or intelligent

12
00:01:24,050 --> 00:01:28,400
systems for the management of the street lighting in cities.

13
00:01:30,920 --> 00:01:38,540
Now, let's talk about the typical software/hardware architecture in which Iot devices are placed.

14
00:01:39,600 --> 00:01:50,550
Iot technology includes four primary components, such as Iot devices, a gateway system, a data storage

15
00:01:50,550 --> 00:02:00,780
system using cloud and the remote control system using mobile apps. Sensors embedded in the Iot devices

16
00:02:00,790 --> 00:02:08,850
sense a wide variety of information from their surroundings, like humidity, temperature, sound

17
00:02:09,210 --> 00:02:13,050
pressure, location, health data, etc..

18
00:02:13,980 --> 00:02:21,570
Gateways are used to bridge the gap between the Iot devices and the internal network and the end user

19
00:02:21,570 --> 00:02:22,980
in the external network.

20
00:02:23,430 --> 00:02:30,320
They send and receive data from the Iot devices to and from the cloud or user.

21
00:02:31,050 --> 00:02:38,850
For example, a smart healing or lightning system installed in a home will be integrated with the gateway,

22
00:02:38,850 --> 00:02:44,720
which helps to connect the device to the Internet and then cloud infrastructure.

23
00:02:47,140 --> 00:02:49,970
OK, this lesson ends here.

24
00:02:49,990 --> 00:02:53,050
Thank you for your kind attention bye
