5 Examples of Internet of Things That Are Changing the World

30 December 2023

By Anthony Jones

The internet of things (IoT) is a term that describes the network of physical objects that are connected to the internet and can communicate with each other and with humans. IoT devices can range from smart home appliances to wearable gadgets to industrial machines. They can collect, process, and share data, as well as perform actions based on commands or conditions. IoT devices can also use artificial intelligence (AI) to learn from their data and improve their performance.


IoT is not a new concept, but it has become more prevalent and powerful in recent years, thanks to the advances in wireless connectivity, cloud computing, and AI. IoT has the potential to transform various aspects of our lives, such as health, education, transportation, agriculture, and entertainment. In this article, I’ll share with you five examples of popular IoT that are changing the world for the better.


1. Smart Cities


Smart cities are urban areas that use digital technologies to enhance the quality of life, sustainability, and economic development of their residents. By collecting and analyzing data from various sources, such as sensors, devices, and citizens, smart cities can optimize the use of resources, improve service delivery, and increase citizen engagement. Some of the benefits of smart cities are:


  • More effective, data-driven decision-making: Smart cities can leverage big data and artificial intelligence to monitor and measure key performance indicators, such as traffic, air quality, energy consumption, and public safety. This enables city officials to make informed decisions based on real-time data and evidence, rather than assumptions or intuition. For example, smart traffic management systems can reduce congestion and emissions by adjusting traffic signals, rerouting vehicles, and providing information to drivers and public transport users.

  • Enhanced citizen and government engagement: Smart cities can use smartphone and connected device technologies to engage and interact with their citizens, as well as to collect their opinions and suggestions. This can increase transparency, responsibility, and trust between the government and the public, as well as create a sense of community and belonging. For example, smart city apps can allow citizens to report issues, access information, request services, and participate in consultations and surveys.

  • Improved sustainability and resilience: Smart cities can use renewable energy sources, smart grids, and smart buildings to reduce their environmental impact and carbon footprint. They can also use sensors and analytics to monitor and manage water, waste, and pollution. Moreover, smart cities can use technology to enhance their preparedness and response to natural disasters, emergencies, and crises, by providing early warning systems, real-time alerts, and coordinated actions.

Some examples of smart cities around the world are Singapore, Barcelona, Amsterdam, and Dubai.


2. Smart Agriculture


Intelligent farming refers to the incorporation of the Internet of Things in agribusiness, with a goal to increase productivity, efficiency, and sustainability. Smart agriculture can use IoT devices to monitor and manage various aspects of crop and livestock production, such as soil moisture, temperature, humidity, pests, diseases, and animal health. Some real-life use cases are smart irrigation systems that water crops according to soil and weather conditions, smart drones that spray pesticides or fertilizers accurately and safely, and smart collars that track and monitor the location, activity, and health of animals.


Smart agriculture can also use IoT to optimize the supply chain, reduce waste, and improve food safety and quality. For instance, intelligent tags can track and confirm the origin, condition, and freshness of food items. Smart fridges can modify their temperature and humidity based on the type and quantity of food they hold. In the same way, smart cooking devices can prepare meals according consumer's flavor preferences or dietary needs.


Smart agriculture is the future of farming, as it allows farmers to maximize yields using minimum resources such as water, fertilizers, seeds, etc. It also offers a comprehensive and holistic approach to address the challenges and opportunities of the agricultural sector in the face of climate change and population growth.


3. Smart Healthcare


IoT in the Healthcare industry improves the delivery and outcomes of health services, while also encouraging patient autonomy and health. This technology can use IoT gadgets for the supervision and treatment of numerous health issues, including chronic illnesses, mental health disorders, and age-related problems. Some examples of smart medical devices used in the health industry are smart glucose monitors that measure blood sugar levels, smart inhalers that track and administer medication for asthma, and smart watches that detect and alert users of irregular heartbeats or falls.


Another significant aspect of smart healthcare is telemedicine, which allows for doctor-patient interaction over the Internet, providing remote consultation, diagnosis opportunity, and treatment advice. This technology can provide additional benefits to individuals who have mobility concerns or reside in areas with limited healthcare access.


AI-based predictive algorithms can play a significant role by analyzing a patient's data and identify potential health risks. This capability allows for quick intervention and preventive approaches to be implemented, potentially minimizing serious health threats and avoiding costly treatments in the future.


While the benefits of smart healthcare are abundant, it also has its challenges, including data protection, patient privacy, and cybersecurity. These obstacles need to be addressed in order to make the implementation and acceptance of the technology more widespread. However, the benefits of improved healthcare accessibility and efficient patient care should not be overlooked. Thus, smart healthcare represents a promising route for the future of health services.


4. Smart Education


Smart education is the integration of IoT into the learning process, aimed at improving the engagement, customization, and efficacy of learning. Smart devices in education can enhance and diversify the interaction between teachers, students, and content, both inside and outside the classroom. For example, smart boards can display and comment on multimedia content, smart tablets can enable interactive and collaborative learning, and smart glasses can provide augmented or virtual reality experiences. 


In addition, intelligent education can employ IoT to gather and examine data on the learning behavior, performance and preferences of students, and use AI to provide feedback, guidance, and suggestions. For example, smart cameras can track and evaluate the attention and emotion of students, smart badges can monitor and reward the attendance and participation of students, and smart tutors can adapt and personalize the curriculum and pace of learning for each student. 


5. Smart Entertainment


IoT technology plays a crucial role in this process, enhancing the content and delivery of various forms of entertainment such as music, movies, games, and sports. For instance, smart speakers can play music based on the user's mood or taste, smart TVs can stream movies based on the user's profile or recommendations, while smart consoles can provide realistic and responsive gaming experiences.


Smart entertainment can also use IoT to connect and engage consumers with each other and with the creators of entertainment. Some examples of IoT entertainment devices are smart headphones that can enable social listening and sharing of music, smart tickets that can provide access and information to live events or smart fan devices that can allow fans to interact with their favorite celebrities or teams.




The internet of things is a powerful and pervasive technology that is transforming the world in many ways. IoT can improve the efficiency, convenience, and quality of various aspects of our lives, as well as create new opportunities and challenges. The examples I’ve shared with you are just a few of the many applications of IoT that are changing the world. I hope you’ve enjoyed reading this article and learned something new.
