• Introduction

IoT refers to the network of connected devices
and the technology that facilitates communication
between devices and the cloud.

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

• Azure IoT Services

• Azure IoT provides lots of valuable services.
  Some of the services that they provide are as
  follows
• Azure IoT Hub
• Azure IoT Central
• Azure Sphere

• 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

• 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. 
• 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. 
• 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.
