Introduction
IoT refers to the network of connected devices and the technology that facilitates 
communication between devices and the cloud.
2
How does IoT work with Azure?
Azure IoT is a powerful tool that enables organizations to deploy, manage and scale IoT 
solutions.
With this you have a bi-directional, trustworthy communication setup, and security is the 
number one priority of this configuration.

Raspberry Pi or Arduino
Raspberry Pi is a microprocessor. The Arduino is a microcontroller.
It is used with whole systems instead of singular It was built to work with other electronic 
electronic components. components and nothing else. Example: 
Wireless Bluetooth modules, motors, etc.
Consists of RAM, Memory card slots, processors, Contains a microcontroller. It has all the 
Graphics controller, ethernet controller, HDMI abilities to store, run and execute programs 
ports, C-type power source, & GPIO pin board. itself.
Raspberry Pi runs on the Linux OS. We can code using the C++ language.

Use Case
Temperature sensor:
• In this use case, an external sensor will 
measure the temperature of its 
surrounding. It will then send that data to 
the Raspberry Pi and display it graphically 
using external tools.

Challenges
1. Data Security 
        IoT devices need to send data to the cloud for processing. This data transfer
        happens through public networks which can result in a breach of the data. 
2. Connectivity  
       In remote areas, where Internet connectivity is not reliable, IoT devices tend to fail
        as they need to process and transfer data to the clouds. 
3. Challenges in Sensing 
       The sensor is a crucial part of any IoT device as any hardware failure can result in less
        accuracy. Data provided by the sensor needs to be precise to generate the
        desired outcome.
