Hi there, welcome back to this course.
Let's start this lesson by defining the Internet of Things.
Internet of Things refers to computing devices that are Web enabled and have the capabilities of sensing,
collecting and sending data, using sensors and communication hardware and processors that are embedded
within the devices.
The slide shows the definition of IoT that Wikipedia provides.
Let's now see what are the typical application areas of Internet of Things devices, the typical areas
in which Iot devices and systems are used, range from industry to healthcare to automation.
For example, let's think about devices for managing home heating, lighting or entertainment.
Other areas of use of Iot devices are the word of wearable devices and the vast world of city automation
think, for example, of systems for the intelligent management of waste or parking lots or intelligent
systems for the management of the street lighting in cities.
Now, let's talk about the typical software/hardware architecture in which Iot devices are placed.
Iot technology includes four primary components, such as Iot devices, a gateway system, a data storage
system using cloud and the remote control system using mobile apps. Sensors embedded in the Iot devices
sense a wide variety of information from their surroundings, like humidity, temperature, sound
pressure, location, health data, etc..
Gateways are used to bridge the gap between the Iot devices and the internal network and the end user
in the external network.
They send and receive data from the Iot devices to and from the cloud or user.
For example, a smart healing or lightning system installed in a home will be integrated with the gateway,
which helps to connect the device to the Internet and then cloud infrastructure.
OK, this lesson ends here.
Thank you for your kind attention bye
