A simple definition of IoT(Internet of Things) is providing the “Internet as a common platform where multiple devices can connect and communicate with each other”.

Applications of IoT

You would be amazed to know that IoT covers almost all domains.The Major Applications of IoT are as follows:


Wearables are small sensor-equipped devices that contain hardware that can sense and read the data. They also contain software to collect and organize information about users.

Google, Apple, and Samsung are the popular brands of wearables. Examples include Virtual Glasses and Smart Watches.

Traffic Monitoring

IoT uses mobile phones as sensors. Mobile phones are used to get information about traffic. They are also helpful in contributing to traffic monitoring . It helps show traffic on routes. It helps to improve information on different routes to the same destination.

IoT helps to produce smart farms. IoT-based sensors detect soil moisture, level of acidity, and temperature of the soil. It helps farmers control irrigation, and discover the presence of diseases in the plant.

Energy Saving

IoT-based intelligent energy meters allow better monitoring of electrical networks. They help in controlling the electrical network. Information obtained from these sensors helps to detect faults, and make repairs.

These Systems also offer information about consumption patterns. It can help user to adjust their energy expenditure.

Importance of IoT in Business

Concerning the Business areas IoT is helpful in the following ways:

  • Improving Customer Experience and Customer Satisfaction
  • Enhancing Employee Productivity
  • Better Decision Making in Business
  • Getting an insight of the performance of machines in operation

Easy Migration to Newer platforms

Java is a flexible language. It is virtually available everywhere. IoT applications are easy to migrate to newer platforms. It leads to lesser errors and issues if you are using java language.

Secure and Scalable

Java is a secure and scalable language. It guarantees the safe and secure functioning of IoT applications over the internet.

Robust Code

Java makes use of objects and the concept of immutability. They cannot be manipulated and thus makes applications robust in nature. IoT applications based on Java are lesser prone to issues such as memory access violation, and buffer overrun.

Rich Libraries in Java

With more than 40,000 libraries in java. It is able to fulfill all IoT requirements. API requires the minimal need to write the code. It leads to quicker code execution for IoT development.

Benefits of Using Java for IoT

  • Java-powered IoT devices prove to be more effective in message exchanging. It effectively helps in message retrieval. It provides better integration as compared to other languages.
  • Java provides automatic up-gradation. It turns out to be cost-effective for IoT development.
  • Java has re-use of modules through various domains.
  • Java has greater accessibility and market reach around the globe. IoT applications get easily viral over the market.
  • Java supports Portability. It is independent of Hardware. This ability helps a lot of IoT applications.

Challenges in IoT


Since IoT applications make use of the Internet as a common platform, There are some challenges and risks faced by IoT applications, they are as follows:

  • Security issues such as Data Leak or Data Breach over the internet.
  • Privacy Issues exist as the Internet is easily accessible to all populations.
  • Updations in IoT applications are greatly constrained to hardware requirements.


IoT is an innovative and revolutionary technology. It can affect various domains such as Machine Learning, Artificial Intelligence. IoT has a wide range of applications in the areas of business, agriculture, wearables, and traffic monitoring. The needs and requirements of IoT are easily fulfilled by Java Language. Features of Java provide Security, Networking, and Portability. These are helpful for the development of IoT applications. Since IoT applications use the internet as a common platform. There is are some challenges faced by IoT applications such as Privacy issues, Updation issues, and the Risk of Data Breaches.
