So, What is the Internet of Technology?

IoT is a vast network of interconnected devices or gadgets. These gadgets collect and share information from the environment in which they are employed. Sensors are present in every physical object and are used in every step of the process.

It may be practically anything you encounter daily, including your cell phone, electrical devices, Pecos barcode sensors, and traffic lights. These sensors continuously release information regarding the devices’ operational status.

What are the Components of IoT?


Cloud is an unavoidable part of the Internet of Things and offers many advantages for IoT apps. Let us see how the cloud works for IoT applications. 

How does the cloud work?

IoT applications need massive data that the cloud collects and processes to relay in the network. Cloud is scalable and manages vast data in a limited infrastructure. Moreover, the cloud is cheaper and more affordable than physical infrastructure. 


The network connects all the components of the IoT. It enables gadgets to exchange data from one component to other. The network helps to clean and arrange the messed-up data. 

Mobile application

The IoT mobile app allows users to manage and operate the gadgets. 

What are the Popular IoT Applications?

IoT has applications in many industries. Let us look at some successful use cases. 


One of the popular IoT applications is Nest for Smart homes. The application allows users to control their home gadgets like thermostats, doorbells, home alarm systems, smart cameras, and more. 

The app offers all the features to automate your home and keeps you updated on how much energy each gadget consumes. 

The application controls devices and sends notifications; for example, it sends an alert if the security alarm goes off. In addition, you can keep an eye on your home remotely, lock the doors, or switch your AC or lights off. 


IoT has touched almost all sectors, including agriculture. With the Blossom app, users can manage their gardens or lawns remotely. The users can schedule the time, and the app automatically waters gardens based on changing weather and the scheduled time. 

The app examines the weather using real-time analytics and the cloud to process that data. Thus, it helps the application decide how much water to plant on the lawns. In addition, the app has different setups for the front yard, back yard, trees, and succulents.


The whistle is an innovative pet-tracking application. Users can use this app to watch their pets, like dogs or cats. The Whistle app allows users to track and monitor their pet’s health and location and stay stress-free. 

They can attach the GPS tracker to their pet’s collar and track them in real time with the Whistle mobile app. 

How to Build an IoT Application? 

Step1: Project Discussion & Planning

The first step to creating anything valuable is thorough discussion and a well-planned strategy. The app discussion covers the following topics:

  • App Development Budget
  • App Requirements
  • Target Audience
  • Competitors Study
  • Current Market trends. 

As a business owner, it is a must for you to have a clear mindset on the above critical topics. When you know your app requirements and budget are reasonable, you will explain them well to the developers. Clean and transparent guidelines about the app’s needs and expectations make it easy for developers to create the exact applications as desired. 

Learning about your target audience gives you a clear idea of what features you want to add to your app. While studying competitors and current market trends will give you a standard idea of the services your customers expect. 

Step 2: Decide The App Development Platform

The next step in developing an IoT application is to decide on its platform. Whether iOS, Android, Azure, Oracle, or cross-platform- which platform do you plan to target? The platform’s decision will depend on your target audience and app budget. 

Step3: Choose the Hardware

An IoT project involves hardware you can either develop or buy from other device makers. Consider these things before choosing the hardware for your IoT application:

  • The hardware should be compatible with your product needs. 
  • Ensure that the data circulates between your app, devices, and the cloud server is protected with end-to-end encryption.
  • Ensure the hardware is reliable and accurate. 
  • Ensure the sensors are of superior quality. 
  • Ensure to separate the services from the API interface for the smooth functioning of your apps on mobile and desktop. 
  • Ensure to choose the technology that supports high scalability. If the app is scalable, it will help you manage an increasing amount of massive data easily. Cloud technology offers greater scalability. 

Step4: Wireframe and Design

App Prototype is essential as it will help you create a quick and error-free design for your IoT application. Once the design and the steps to follow to make the app are straightforward, there will be fewer chances of errors. 

The designers and the developers will know the whole plan to follow during app development. The idea of the design guidelines for the app architecture will be clear to avoid errors and reworks. Thus, it helps develop the application quickly with fewer errors and costs. 

Step 5: Internet of Things App Development

After proper planning, design and app prototype, and hardware, what is the next thing you need?

Step 6: Testing

The next step in developing an IoT app is checking the quality of codes. Quality assurance ensures that there are no errors or loopholes in the application. The quality assurance engineers will test the following:

  • If the code is free of errors.
  • Whether or not the app is compatible with the hardware. 
  • If the app is secure from cyber threats

Various automated and manual tests help fix the above loopholes in the application. 

Step6: Deployment and Maintenance

How much does it Cost to Build an IoT Application?

The cost of developing an IoT application varies depending on your app’s features, technologies, and the developer’s hourly costs. Let us look at the factors that affect the cost of IoT application development. 

Features & Third-party Integrations

The number and the complexity of features directly affect the cost. Higher will be the cost of developing your app with more complex features. The price will go higher if you have more integrations and APIs. 

Hourly Development Rate The most

The primary factor affecting the cost of an IoT application is how much your development agency charges you. The hourly rate of developers is different in every region or country. If you plan to outsource an IoT app development agency, you can think of countries like India, Ukraine, etc. 

These countries have cheaper hourly developer rates than the USA, Europe, etc.
