IOT: Introducing the Internet of Things

What is the Internet of Things (IoT)?

The term IoT or Internet of Things refers to the network of smart devices and technologies that facilitate communication between devices and the cloud and between devices. Thanks to the advent of low-cost computer chips and high-bandwidth telecommunications technology, today, we have billions of devices connected to the internet. This means everyday devices like toothbrushes, vacuums, cars and machines can use sensors to intelligently collect data and respond to users.

The Internet of Things integrates “things” with the Internet every day. Computer engineers have been adding sensors and processors to everyday objects since the 90s. However, early progress was slow because the chips were large and cumbersome. Low-power computer chips called RFID tags were first used to track expensive devices. As the size of computing devices shrinks, these chips also get smaller, faster, and smarter over time.

The cost of integrating computing power into small items has now dropped dramatically. For example, you can add connectivity with features of Alexa voice service to MCUs with less than 1MB of RAM built-in, such as for light switches. An entire industry has suddenly emerged with a focus around putting IoT devices in every corner of our homes, businesses, and offices. These smart gadgets can automatically transmit and receive data over the Internet. All these “invisible computing devices” and the technology involved are collectively known as the Internet of Things.

How does IoT work?

A typical IoT system works through real-time data collection and exchange. An IoT system has three components:

Smart device

This is a device, like a television, security camera, or exercise equipment that has been given computing power. The device collects data from its surroundings, user input, or usage patterns, and transmits and receives data over the Internet from its IoT application.

IoT Application

An IoT application is a collection of services and software that integrates data received from different IoT devices. This application uses machine learning or artificial intelligence (AI) technology to analyze data and make informed decisions. These decisions are transmitted back to the IoT device, and the IoT device then intelligently responds to the input.

Graphical User Interface

One or a group of IoT devices can be managed through a graphical user interface. Common examples include a mobile app or website that can be used to register and control smart devices.

Some examples of IoT devices?

Let’s take a look at some examples of IoT systems in use today:

Smart Car

Vehicles, such as cars, can connect to the Internet in many ways. It can be through smart dash cams, infotainment systems or even through the vehicle’s connection port. They collect data from the accelerator, brakes, tachometer, odometer, wheels and fuel tank to monitor both driver performance and vehicle condition. Smart cars are used for a range of purposes:

• Monitor rental car fleets to increase fuel efficiency and reduce costs.
• Help parents monitor their children’s driving behavior.
• Automatically notify friends and family in the event of a car accident.
• Anticipate and limit vehicle maintenance needs.

Smart Home

Smart home devices focus primarily on improving the efficiency and safety of the home, as well as the connected home network. Devices like smart drives can monitor power usage and smart thermostats can provide better temperature control. Hydroponic systems can use IoT sensors to manage the garden, while IoT smoke detectors can detect cigarette smoke. Home security systems like door locks, security cameras and leak detectors can detect and stop hazards and send alerts to homeowners.

Families can use smart devices for the following purposes:

• Automatically turn off devices when not in use.
• Management and maintenance of rental properties.
• Find lost items like keys or wallets.
• Automate everyday tasks like vacuuming, making coffee, and more.

A smart city

IoT applications have made urban planning and infrastructure maintenance more efficient. Governments are using IoT applications to solve infrastructure, health and environmental problems. IoT applications can be used for the following purposes:

• Measure air quality and radiation levels.
• Reduce energy costs with smart lighting.
• Determine when to maintain critical infrastructure like roads
• Increase profits through efficient parking management.

Smart construction

Buildings like university campuses and commercial buildings use IoT applications to drive more efficient operations. Smart buildings can use IoT devices for:

• Reduce energy consumption.
• Reduce maintenance costs.
• Make the most of your workspace.

What is Industrial IoT?

Industrial IoT (IIoT) refers to smart devices used in manufacturing, retail, healthcare, and other fields to generate business efficiency. Industrial devices, from sensors to machines, provide business owners with detailed, real-time data that businesses can use to improve business processes. These devices provide insights into supply chain management, logistics, human resources, and manufacturing – reducing costs and increasing revenue streams.

Let’s explore intelligent industrial systems in different verticals:

Manufacture

Enterprise IoT in manufacturing uses predictive maintenance to reduce unplanned downtime and wearable technology to improve worker safety. IoT applications can predict a machine failure before it occurs, helping to reduce production downtime. Helmets and wristbands, as well as computer vision cameras, are used to warn workers of potential hazards.

Automotive industry

Sensor- and robotic-driven analytics increase efficiency in automotive manufacturing and maintenance. For example, industrial sensors are used to provide real-time 3D images of vehicle interior components. Diagnostics and troubleshooting can be done much faster while the IoT system automatically orders spare parts.

Logistics and transportation

Commercial and industrial IoT devices can assist with supply chain management, including inventory management, supplier relationships, fleet management, and scheduled maintenance. Shipping companies use industrial IoT applications to track assets and optimize fuel consumption on shipping routes. This technology is particularly useful for tightly controlling temperatures in refrigerated containers. Thanks to intelligent routing and rerouting algorithms, supply chain managers can make informed predictions.

Retail

Amazon is driving innovation that automates and collaborates between people and machines in retail. Amazon facilities use Internet-connected robots to track, locate, sort, and ship products.

How can IoT improve our lives?

The Internet of Things has a profound impact on people’s lives and work. IoT enables machines to do the heavy lifting, take on mundane tasks, and make life healthier, more productive, and more comfortable.

For example, smart devices can completely change your morning routine. When you press the snooze button, your alarm clock will automatically turn on the coffee maker and pull open the window blinds. Your refrigerator will automatically detect which food is running low and order it for home delivery. The smart oven will tell you the menu of the day and even cook pre-prepared ingredients to make sure your lunch is ready. The smartwatch will schedule your meeting, while your smart car automatically sets the GPS location to stop the car to refuel. The potential is limitless in the IoT world!

What are the benefits of IoT for businesses?

Speed up innovation

The Internet of Things gives businesses access to advanced analytics to uncover new opportunities. For example, businesses can create well-targeted marketing campaigns by collecting data on customer behavior.

Transform data into insights and action using AI and ML

Collected past data and trends can be used to predict future outcomes. For example, warranty information can be paired with data collected by the IoT to predict maintenance issues. This advantage can be used to proactively provide customer service as well as build guest loyalty.

Increased security

Continuous monitoring of digital and physical infrastructure can optimize performance, improve efficiency, and reduce safety risks. For example, data collected from an on-site monitoring device can be combined with hardware and firmware version data to automatically schedule system updates. Scale up differentiated solutions IoT technology can be implemented in a customer-centric manner to improve satisfaction. For example, hot-selling products can be replenished in time to avoid stock shortages.

What are IoT technologies?

Technologies used in an IoT system may include:

Edge computing

Edge computing refers to technology used to control smart devices to do more than simply send or receive data from their IoT platform. This technology increases computing power at the edge of an IoT network, reducing communication latency and improving response speed.

Cloud computing

Cloud technology is used to remotely store data and manage IoT devices, making data accessible to multiple devices in the network.
