Quick Summary: In this blog, we are going to discuss what is IoT, how to develop an IoT app, and what are the things to keep in mind while developing an IoT app of the future that will turn the tables and profit from this platform. So without any further ado, let’s get started!

The 21st century has outshined many people’s imaginations with mind-blowing innovations to this revolution of IoT development. Despite this, not all developers are familiar with IoT app development. According to an anonymous survey, the IoT devices are expected to increase to 100 billion from 75 billion at the end of 2030, and few improvements in 4G connectivity which will be updated to 5G in terms of increasing IoT is crucial.

A survey conducted by Mordor Intelligence,  the global IoT market is expected to increase at the end of 2026 from USD 761.4 billion to USD 1,386.06 billion.

What Is An Internet of Things?

Layman’s language defines IoT as a process where all the components are interconnected with each other via a network that uses special electronic equipment. In other words, IoT is a

It is an analogous network that connects real-world objects and supports the information exchanged between them without human efforts. Its concept is highly popular in mobile software development that significantly simplifies our everyday lives.

In short, IoT is global support for the information society that contributes exceptional services which are associated together based on the evolving interoperable information and communication technologies.

 IoT Testimonies and Forecasts says the truth:

2020: $24 billion IoT units worldwide

2020: $267 B2B will spend on IoT

2025: $75 billion over 10 devices per person worldwide

2025: $13 trillion revenue from IoT implementation

What Are The 7 Layers Of IoT Development?

1. Perception Layer

The perception Layer is the topmost layer of IoT architecture. In this layer, there are multiple sensors and actuators used that gather information and pass the data to another layer so that actions can be taken based on that information.

2. Network Layer

The next layer that comes after the Perception layer is the Network layer that merges the layer between perception and the middleware layer via networking technologies which is also called the communication layer. This layer helps to transfer data securely and keep it confidential.

3. Middleware Layer

Middleware Layer offers advanced features such as capabilities to take actions, computation, processing and much more. This layer stores your device address and provides an appropriate name to that device that is obtained from sensors.

4. Application Layer

Last but not the least, the Application layer manages all your application-based processes that have information from the middleware layer.

5. Business Layer

At last comes the Business layer that performs the programming tasks embedded within the apps like creating graphs, improving devices, generating flowcharts, and much more.

How To Develop An IoT App?

1. Choose the Suitable Platform for IoT App Development

When it comes to apps, there are multiple options available for application development. You can pick the one that is suitable for your business and focuses on what innovations they support and how much it’ll cost. To make it easier to choose the right platform for app development, here are few top platforms from which you can pick any and start your development process:

  • Oracle IoT
  • HomeKit
  • Kaa
  • Android Things
  • Ubidots
  • ThingWorx
  • Azure IoT Suite
  • Xively
  • IBM Watson

These IoT development platforms try to resolve the complex issue in the process of application development that allows IoT developers to link devices from various vendors that implement different procedures into one unified system.

2. Choose the Hardware

You need to select equipment from other device markets if you’re not producing your hardware for application development. It is important to check whether the tools you’re selecting represent your product’s requirements and is it reliable for your project’s success. So, while selecting the hardware make sure that the project is trustworthy and guarantees high-quality IoT applications.

You should also choose application development boards for Smart Bluetooth and WiFi from microcontroller-based boards like:

  • Arduino Uno
  • C.H.I.P
  • Raspberry Pi
  • Mediatek Linkit One
  • Intel Edison
  • Particle Photon
  • Udoo Neo
  • Tessel
  • LightBlue Bean
  • Adafruit Flora

3. Check for Scalability

For application development, you must check the scalability in advance because your app will undoubtedly stay relevant depending much on it. It takes care of various devices, procedures, and increasing amounts of data.

4. Check Whether Your IoT Application Is Quick or Not

Every IoT app needs to be incredibly quick. IoT mobile apps are developed to share information from one location to another where the rate of each lag is too high.

Imagine, there is a connected auto that won’t immediately respond to your commands, which will result in losing your potential customers. Therefore, it is said that performance and speed are the two main factors for application development.

5. Use Security Tools

Safety and security of your software is the main concern when it comes to developing a software application that protects your software app. As we all know that IoT apps are developed to share information where multiple devices share a single network, so the risk of losing data increases. Therefore, using security tools is important.

 Here are a few couples of ideas to ensure security in your software application:

  • Choose hardware vendors carefully
  • Use proved IoT platforms for apps
  • Think about network assaults and physical assaults
  • Use protected networks
  • Apply best practices for app security

From various locations where people use IoT apps the most; healthcare devices, their cars and trucks, and residences — these attacks can lead to exposing your personal and sensitive information also. So, make sure that you are utilizing security tools while developing your IoT application.

 Before discussing the main components of IoT, let’s know about the benefits you’ll get while deploying an IoT application:

  • Optimize resource consumption
  • Enhance business opportunities
  • New revenue streams
  • Leverage real-time control
  • Excellent customer experience
  • Improve control of operation processes
  • Tracking real-time market behavior
  • Mobility and agility
  • Fine tune services and products
  • Improve monitoring
  • Efficiency and productivity
  • New capabilities to act

What Are The Main Components Of IoT?

Every IoT system consists of four main components:

1. Hardware

The hardware is the main component for every IoT system that offers sensors with low-energy and works over Bluetooth to connect to the internet. You need to check whether you require custom hardware or third-party hardware to implement your idea in your IoT system.

2. Software

Your IoT system must consist of cloud-based software whether it is for web or mobile, that’s simply a dashboard that manages all IoT devices connected to it and also gathers information from sensors and shows it to users.

3. Cloud

For IoT software application development, Cloud is the most important technology because it processes the data and manages it. Using cloud technology doesn’t require any physical resources for storing and managing your data.

4. Network

For sharing mobile app data from one location to another, a network is required through which the data can be transmitted. These devices are linked in mobile apps within the IoT system.


Various tools and training resources will allow you to develop an IoT software application easily and in a relatively short time. The development of IoT applications will grow in the coming years and this indicates the great potential of the IoT ecosystem. IoT is one of the most promising sectors in the IT industry that help materialize each customer’s vision and experience.

The demand for developing IoT software applications is increasing day by day. It sets people’s lives free and the necessity to remember little things. Network stability, security, and speed are the three important considerations that should be kept in mind while developing an IoT app.
