Internet of Things

The Internet of Things (IoT) is the network of

interconnected physical devices, objects, or

"things" embedded with sensors, software, and

connectivity, allowing them to collect and

exchange data over the internet.

Evolution of IoT

Devices that collect

data from the physical

world. (eg. velocity, GPS

coordinates,

temperature, etc...).

Devices that perform

actions based on data.

(eg. Motors , servo , etc..)

Embedded computing

units that process data.

• Embedded computing

units that manage IoT

devices.

• Process sensor data

and control actuators.

• Common

microcontroller

platforms (e.g.,

Arduino, Raspberry Pi).

successively the data

collected is sent to the cloud

(through either WiFi or

Bluetooth connection).

once the data is received

by the cloud infrastructure,

it can then be processed (eg.

check if the data received

adhere to the requirements

and if its not alert the user).

Once the data is

processed, the results are

then given to the and user.

Sensors are the primary means of

collecting data from the physical world. They can

detect and measure a wide range of parameters

such as temperature, humidity, pressure, motion,

light, and more. This data forms the foundation for

informed decision-making.

Sensors enable real-time

monitoring of physical environments and processes.

This is vital in applications like environmental

monitoring, industrial automation, and healthcare,

where instant data updates are critical.
