The Internet of Things (IoT) is a network of interconnected, embedded devices that can capture and transmit data without the need for human interaction over a wireless network. 

IoT applications in everyday life include smart wearables, smart health monitoring, traffic monitoring, IoT in agriculture with many sensors, smart devices, robots in hospitals, smart grid and water supply, and so on.


  • It can assist in the smarter control of homes and cities via mobile phones. It enhances security and offers personal protection.
  • By automating activities, it saves us a lot of time.
  • Information is easily accessible, even if we are far away from our actual location, and it is updated frequently in real time.
  • Electric Devices are directly connected and communicate with a controller computer, such as a cell phone, resulting in efficient electricity use. As a result, there will be no unnecessary use of electricity  equipment.
  • Personal assistance can be provided by IoT apps, which can alert you to your regular plans.
  • It is useful for safety because it senses any potential danger and warns users.   For example, GM OnStar, is a integrated device that system which identifies a car crash or accident on road. It immediately makes a call if an accident or crash is found.
  • It minimizes human effort because IoT devices connect and communicate with one another and perform a variety of tasks without the need for human intervention.
  • Patient care can be performed more effectively in real time without the need for a doctor’s visit. It gives them the ability to make choices as well as provide evidence-based care.
  • Asset tracking, traffic or transportation tracking, inventory control, delivery, surveillance, individual order tracking, and customer management can all be made more cost-effective with the right tracking system.

IOT Advantages


  • Hackers may gain access to the system and steal personal information. Since we add so many devices to the internet, there is a risk that our information as it can be misused.
  • They rely heavily on the internet and are unable to function effectively without it.
  • With the complexity of systems, there are many ways for them to fail.
  • We lose control of our lives—our lives will be fully controlled and reliant on technology.
  • Overuse of the Internet and technology makes people unintelligent because they rely on smart devices instead of doing physical work, causing them to become lazy.
  • Unskilled workers are at a high risk of losing their jobs, which could lead to unemployment. Smart surveillance cameras, robots, smart ironing systems, smart washing machines, and other facilities are replacing security guards, maids, ironmen, and dry-cleaning services etc.
  • It is very difficult to plan, build, manage, and enable a broad technology to IoT framework.
  • Deploying IoT devices is very costly and time-consuming.
