Exploring the Internet of Things (IoT): An Introduction to Embedded Systems Integration

Technology has made significant progress and has blurred the lines between sectors, resulting in the terms Internet of Things (IoT) and embedded systems being used interchangeably, despite their differences. 

Embedded systems were introduced in 1965 by Autonetics, who developed a miniature computer for missile guidance systems. These systems operate independently and are tailored to perform specific tasks. Contrastingly, IoT-embedded systems are embedded systems with added connectivity to the internet, allowing them to communicate with other IoT-embedded systems. IoT-embedded systems surround us daily, such as point-of-sale terminals, set-top boxes, medical devices, bicycles, refrigerators, and fitness trackers. Even parking metres and other similar devices are now IoT-enabled.

What Are Embedded Systems in the Context of IoT?

An IoT embedded system, also known as a "smart" device, is an embedded system incorporating internet connectivity. While the presence of a touch screen or keyboard can enhance its functionality, these peripherals are optional for defining a device as an IoT-embedded system.

IoT Embedded Systems: Types

An embedded system for IoT is equipped with specialized software that enables it to perform its intended functions. This software can take the form of firmware or an embedded operating system. This software empowers the IoT-embedded system to communicate and interact with other IoT-embedded devices.

The term "embedded devices" is often used interchangeably within embedded systems. However, it is essential to note that embedded devices typically comprise a more extensive embedded system designed for IoT applications. Embedded devices are highly specialized devices with a specific purpose or a limited range of functions. They are also referred to as Dedicated Devices or Single Purpose Devices. These devices serve as IoT-embedded systems that have been purpose-built to execute a program or perform tasks tailored to specific businesses.

Here are some examples of single-purpose IoT embedded systems:

• Self-checkout systems
• POS (Point of Sales) systems
• Kiosk systems

IoT Embedded Systems: Use Cases

IoT devices' hardware component is the embedded system, which is the foundation for their functionality. Utilizing the same hardware as personal computers for building IoT devices would be costly and unnecessary. Fortunately, the availability of embedded systems such as SBC (Single Board Computers) like Rock Pi 4B and Raspberry Pi enables the creation of IoT computing devices on a smaller scale while keeping costs low.

Here are several popular use cases that showcase the versatility of IoT-embedded system devices:

• POS Terminals

IoT-embedded systems are commonly used in Point-of-Sale terminals and self-service checkout systems. These touch-enabled devices connect to payment gateways via the Internet to process transactions. Scanners can also interact with pin pads and card readers for seamless payment processing.

• Vending Machines

IoT-embedded systems in vending machines can utilize connectivity to alert employees when items need to be restocked. These devices can include inputs such as coin slots capable of recognizing different coin types, touch screens for user interaction, and credit card readers for additional payment options.

• Ticket Scanners

Event venues can employ IoT-embedded systems as ticket scanners. These devices read ticket information from visitors, compare it with a local or online database, and then activate turnstiles to allow entry. Additionally, these systems can be programmed to send attendance data to analytics platforms, providing valuable insights to event organizers.

By leveraging the capabilities of IoT-embedded systems, these devices can perform their primary functions and gather and transmit valuable data for further analysis and decision-making.
