How Does the Internet of Things Work: Benefits, Use Cases, and More

The internet of things, also known as the IoT, is a system of interconnected devices and sensors that can collect and exchange data. The IoT has the potential to revolutionize the way we live, work, and play by connecting devices and people in new and innovative ways. Companies are developing products and providing services that leverage the IoT’s ability to deliver timely, relevant information and solutions.

The potential of an interconnected world is greater than ever before. But how does the internet of things work? What is it? And what does it mean for you? In this article, we’ll answer these questions and more.

What Is the Internet of Things


Kevin Ashton, a British technologist, created the term “Internet of Things” in 1999. Sometimes referred to as machine-to-machine (M2M) communication, the IoT takes digital technology into the real world.

The IoT enables everyday objects [with sensors] to collect and share data, which can be used to make decisions or take actions. For example, a smart wearable device might track a person’s physical activity or location.

The sensor data could then be transmitted via an app to their health care provider so they can monitor a patient’s progress. In addition, someone may have smart lights in their home that allow them to control lighting remotely with their smartphone and/or voice commands.

The IoT is made up of a variety of connected devices such as sensors, computers, network devices, and more. Sensors include devices that capture physical data that can be used to measure or monitor certain conditions.

A sensor could be a digital thermometer inside a dishwasher that sends its measured temperature to a cloud-based app that collects the information and gives it to the dishwasher’s manufacturer so they can make adjustments based on the information they have gathered. Smart cameras can also serve as sensors by sending the data from their images and videos to various databases for processing.

How Does the Internet of Things Work

The IoT involves creating a network of connected devices that can share data and communicate with each other.


Sensors, actuators, and other devices that collect information about the environment. The IoT may also include smart wearable technology such as wearables or fitness trackers.


One Internet of Things device communicates with another via Internet transfer protocols. A means of transmitting data between devices, such as cellular Internet connections or local area networks (LANs).


Software that runs on devices to capture and transmit data and allow them to connect with other devices.

Embedded Software

Devices in an IoT system typically send messages over LANs with the help of embedded software. The IoT design imposes very little control or management from the central network, which means that devices can talk to each other without any relaying from a central network controller.

For example, sensors on a manufacturing plant floor may be able to detect when machinery malfunctions or when dangerous conditions exist. Such signals may be sent directly to an end user’s device or to intermediate devices such as a manufacturing control system.

The embedded software may produce diagnostic information that includes the type of problem, the location, and the severity. The information can then be passed along to the maintenance personnel for action.

According to Statista, by the end of 2020, there will be about 31 billion connected smartphones, wearables, smartwatches, automobiles, and other devices.

Benefits of The IoT


1. Localization

The IoT can help you improve the way you navigate and find your way around unfamiliar places. For example, companies are developing smart maps that can show a user where they are, what is nearby, and how to get there.

This information is based on where they are, as well as their GPS location, and comparisons of what’s nearby with local businesses’ locations and hours of operation. These maps can be accessed on mobile devices or dashboard displays in vehicles.

Other companies are using the IoT to improve navigation inside buildings. For instance, in a large supermarket, there may be hundreds of products on the shelves. A device that communicates with sensors placed on products could use machine vision to identify each item and then communicate with a local device to provide information on where it can be found.

2. Security and Monitoring

Today’s technology offers many ways to monitor and protect people, places, and things. The IoT uses sensors to recognize unusual patterns or detect events as they happen. For example, if a smoke sensor detects smoke or fire in a home or business, it can send an alert to the fire department so they can take appropriate action.

A smart thermostat has sensors that monitor the building’s temperature, and then it can automatically adjust the temperature based on a homeowner’s preferences.

The IoT also can be used to protect people who travel. For example, smart car systems may use sensors to detect potential hazards that are close by and guide drivers to prevent accidents. In addition, cargo ships and aircraft have sensors on board to detect dangerous conditions before they threaten the safety of those onboard or nearby.

3. Home Automation

The IoT can be used for home automation and energy management. For example, a person may have sensors in their home that can monitor the temperature and humidity. The sensors can schedule actions based on the conditions such as turning on the air conditioner when it gets too hot or adjusting the thermostat based on a person’s schedule and preferences.

Smart devices also can help homeowners save money by assessing energy usage in their homes and helping them conserve electricity. For instance, they could evaluate how much power is required to run appliances or lights and then notify users when they need to unplug certain items. Some devices can perform simple tasks such as turning off a light or appliance when the homeowner leaves the room or after a set amount of time.

4. Health and Medicine

The IoT can be used to improve the quality of life for some people by collecting and sharing data from sensors in homes, offices, factories, vehicles, and elsewhere. In healthcare, sensors can be readily integrated into wearables that measure vital signs such as heart rate, breathing rate, temperature, and more.

This information is sent to a patient’s health care provider (e.g., doctors) using the Internet to access their patient’s information anywhere at any time.

5. Security and Monitoring of Assets

The IoT can also be used to monitor traffic, security, and other information about assets as diverse as buildings, vehicles, ships, and airplanes. For instance, sensors placed on a building’s windows can detect when they are broken or insects are coming inside via a window or door.

This information can be used to notify emergency services or even the owner if it is necessary. In addition to monitoring the physical environment, sensors can also be used for remote tracking and analysis of assets, such as vehicles and aircraft.

For example, sensors on a shipping cargo ship can be used to detect dangerous conditions and send signals to warn the crew of an impending problem. Airline companies are using sensors to track their planes as they travel around the world, while self-driving cars may use sensors that transmit information about their surroundings as well as how fast they are traveling.

The IoT can also be used for security and surveillance, including protecting infrastructure such as power supply systems from cyberattacks by detecting unauthorized attempts to access or damage equipment.

6. Energy Consumption Management

The IoT can be used for energy management by collecting and analyzing data about energy usage in buildings and vehicles. For example, sensors may be placed on light bulbs, appliances, and other devices to determine when they are being used and how much energy they consume.

This information can provide insight into where energy is being wasted or poorly utilized. In addition, systems can be designed to adjust the energy consumption of devices based on the amount of power available.

For instance, if a building has a low amount of electricity during peak hours, an IoT system can reduce the use of smart appliances in response to that information.

7. More Flexibility and Adaptability

The IoT allows for much more flexibility and adaptability than traditional networks typically allow because each device has its own network interface such as Wi-Fi, Bluetooth, or cell phones with built-in Wi-Fi networks.

This means that devices can connect to each other directly rather than through gateways that relay messages from one device to another. It also means that every device can have a unique address (e.g. cellular phone number) and are able to communicate outside the local area network.

8. Facilitates Communication Between Devices

The IoT facilitates communication between devices that are part of the same system and also communication between systems such as a home automation system, heating system, and lighting system.

The former allows devices within the same application to communicate with each other, such as smart light bulbs that can turn on or off based on information from connected sensors or other smart devices.

The latter allows data from one device to be used by another connected device. For instance, a motion sensor could trigger an alarm for a surveillance camera using an edge device in the network, which may then transmit a video feed to another edge device that is tied into security software.

In addition, the IoT contains troves of personal information about individuals, such as their location, activity patterns, and more.

The Use Cases of the IoT


As stated earlier, the IoT is being used to create a network of connected devices and computers in the physical world. According to a Business Insider report, 24 billion IoT devices will be installed by 2020. Below are examples of some of the use cases that are currently being explored:

Smart Cities

The IoT is intended to be used in smart cities, which use devices to monitor and control aspects of their environments. For example, sensors may be used by city planners to detect pollution levels around a city or track when and where water is being wasted.

The IoT can also be used for public health purposes, such as monitoring elderly individuals’ health status based on information from their medical care providers. Sensors can also be placed on vehicles to detect road defects (e.g. potholes) and on public transit, vehicles to track vehicle performance.

Smart Agriculture

Using sensors and other devices, IoT systems can monitor various aspects of agriculture. For example, sensors may be used to monitor soil moisture levels and temperature conditions at an irrigation system’s hydrology panel or to monitor the water consumption of a greenhouse.

Sensors can also be used in outdoor farming operations to detect soil moisture or plant health levels via vibration. The IoT could also be used for precision agriculture, which involves using newly developed technologies such as drones with cameras or sensors that are automatically guided to specific targets using GPS positioning systems.

Aspects such as weather conditions, crop yields, and time-lapse photography can be monitored with precision agriculture devices.

Smart Transportation

A Smart Transportation system can monitor for instances of congestion in a city. Sensors can also be used to detect vehicle emissions and the status of vehicle parts. The IoT can also be used to control the temperature of vehicles such as heaters and air conditioning systems, as well as turn signals, brakes, and horn functions.

Smart Manufacturing

The IoT is intended to help manufacturers monitor the flow of raw materials and finished goods within their manufacturing processes. For instance, sensors may be used to identify anomalies or changes in process flows by observing variations in inventory levels at ovens or other equipment that can produce components.

The IoT also can be used to improve safety and worker productivity. For example, sensors can detect when workers are struggling with heavy equipment and automatically transmit that information to mobile devices which relay it to supervisors.

In this case, the sensors are integrated into a fully automated system such as a robotics arm or an assembly line. Sensors measure these values in order to ensure that machines are not damaged by overheating parts or in other ways may compromise the quality of products during production.

Smart Homes/Eliminating Security Issues

Smart homes are one of the most contemplated uses of IoT. Since IoT is a network of physical devices, it allows for monitoring and controlling a large array of home automation devices such as lights, appliances, HVAC systems, and security systems. At some point in the future, the use of the IoT will become more common in home automation.

A significant benefit of using smart devices is that the flow of energy into the house can be controlled automatically and even saved. In addition to providing comfort to residents, this system helps energy efficiency which saves energy bills and reduces carbon footprints from power plants.

The role of a smart device also is to reduce any unwanted intrusions by criminals. Smart devices can have multiple levels of security and in some cases, voice control to automatically enter a coded code.

There are multiple ways that smart homes can be used. For example, one way is by using home automation apps that allow users to remotely control their devices from the safety of their desktops or mobile devices. Another way is by controlling fan speeds, thermostats, or lights through voice commands.

The IoT can also be used to reduce the cost of electric vehicles and power grids. For example, Energy Storage Systems (ESS) offers more efficient ways of storing solar energy for use on cloudy days and nighttime hours.

The Impact of the IoT

The IoT has the potential to create a lot of new jobs, create economic opportunities (e.g. smart cities), and save money on energy consumption costs and production costs due to increased automation and efficiency of machinery. According to ITC, IoT sales will exceed $300 billion in the future years.

As the number of connected devices continues to grow, security is becoming an increasingly important issue, as hackers are given more opportunities to exploit vulnerabilities in software to gain access to networks of vulnerable machines.

The Internet of Things (IoT) ecosystem is growing rapidly as more and more devices are connected to the internet. A key part of this ecosystem is data processing, which refers to the collection and analysis of data from networked devices. This data can be used to improve the performance of IoT platforms and devices, and to better understand the behavior of users.

The use of wearable devices has been on the rise in recent years, thanks in part to advances in IoT technology. These devices are often equipped with sensors that can collect a variety of data points, which are then transferred to a user interface for analysis. This data can be used to track fitness levels, monitor heart rate, and more.

Future of IoT


IoT devices can add a lot of value to the consumer and business worlds, but current issues must be fixed to fully optimize their use. One main issue is that while devices can connect seamlessly in an IoT system, there are still a lot of challenges behind the scenes that need to be taken care of, such as connecting devices securely and ensuring data privacy when transmitting them across networks.

Furthermore, between 2018 and 2026, businesses and individuals will spend nearly $15 trillion on IoT devices, solutions, and supporting infrastructure.

Even though the Internet of things has helped with home automation, it doesn’t support all features that most homeowners would experience in a traditional home setup. Smart home technology is still in its early stages, and there are many areas of improvement to look forward to.

The IoT will have a major impact on the way people live and work in the future. As more devices become connected to the IoT, a bigger network of devices will be created. Therefore, security becomes more critical than ever.

As new IoT technologies continue to be developed, they will bring new changes and improvements to society as a whole. For example, driverless cars not only improve transportation services but also reduce traffic accidents caused by human mistakes.

As the world becomes more connected, web-enabled devices are becoming increasingly prevalent. Other connected devices, such as IoT platforms and IoT devices, are interrelated computing devices that enable communication and collaboration between devices.
