The birth of the Internet of Things (IoT) is rooted in the development of radio frequency identification (RFID) technology and the invention of the internet in the mid-1990s. This invention allowed for the possibility of connecting physical objects to the web and harnessing the power of connected devices. In the 2000s, these early ideas began to gain traction, thanks to the development of wireless technologies and the proliferation of small, low-power embedded devices. This allowed everyday objects like appliances, cars, and even clothing to connect to the internet.

The emergence of the IoT became a reality in the 2010s, as advances in wireless technologies and cloud computing enabled companies to create large-scale, interconnected networks of smart devices. This allowed for the development of smart cities, as well as the growth of smart homes and connected healthcare offerings. Today, the IoT is revolutionizing the way we interact with the world and improving people’s lives everywhere. From connected cars to smart homes to connected healthcare, the possibilities of the IoT are virtually limitless.

What is IoT?

Internet of Things (IoT) is a revolutionary concept changing how we interact with the world around us. IoT is an interconnected network of physical objects – such as sensors, electronic appliances, and everyday items – that are embedded with electronics, software, and sensors and are capable of collecting and exchanging data over the Internet. These objects are connected to a wide range of wireless networks and can communicate with one another without needing any human intervention.

At its core, the concept of IoT is to provide an infrastructure that allows for more efficient, secure, and automated communication and control of physical objects and systems. This is achieved through intelligent sensors and actuators, allowing real-time data collection and analysis. This data can then be used to make decisions, automate processes, and provide feedback to users. In addition, IoT networks also use cloud computing, machine learning, and artificial intelligence to provide more powerful and efficient analytics.

The potential of IoT is immense, and it is already being used to improve our lives in many ways. From smart homes to connected cars, IoT is making our lives easier, safer, and more efficient. The possibilities are endless, and the future of IoT is bright.

Essential Requirements for IoT App Development

Cloud technology, dedicated hardware, a reliable network, and intuitive software – are the four primary requirements for any IoT Application Development.

  • Cloud technology provides the infrastructure for connecting all the different elements of the Internet of Things (IoT) application. This could include cloud-based storage solutions or a cloud platform for managing the data generated by IoT devices. 
  • Dedicated hardware are the system’s physical components, such as sensors, gateways, and controllers. They are responsible for collecting and transmitting data from the environment. 
  • A reliable network is necessary to ensure the data collected from the hardware components is transmitted to the cloud on time. This could be locally based (LAN) or spread widely (WAN) like the Internet. 

Finally, intuitive software is required to manage the data collected by the hardware components and display it in a user-friendly way. This could include dashboards, analytics, and visualization tools.

IoT App Development Process

Developing IoT applications is very dynamic; and usually depends on the scale, customizations, and functionalities you seek from the app. Nevertheless, the following five steps can explain most IoT applications’ developmental methodology:

iot app development process

Step 1: Ideation and Requirements Gathering

This is the first step in the development process. It involves brainstorming ideas and collecting requirements specific to the scope and features of the application. 

Discuss with your team and stakeholders what you need the app for. Do you want a service app? Perhaps a records keeper? Or an app that tabularizes your daily power consumption?

Think. Rethink. And only then Finalize.

Once finalized, you must acquire the necessary funding, obtain the permits, and secure the required technical and support resources to drive your concept to reality.

Step 2: Design/Prototyping

This is when the application is designed and a prototype is created. The designing phase requires understanding the intricacies of user interface and user experience (UI/UX). A well-thought-out design distinguishes a successful app from one that fails quickly.

Users should be able to easily navigate the app without guessing their way around. Moreover, the flow should be comprehensible and logical, and there should be no broken links or buttons that don’t lead anywhere. Ultimately, the app should feel natural and intuitive to use.

Step 3: Hardware and Software Selection

The next step is to select the proper hardware and software components. Hardware for IoT development usually includes :

  • microcontrollers, 
  • sensors, and 
  • communication interfaces

Software components include:

  • Operating systems (Zephyr, Linux, Android Things, etc.), 
  • Development platforms (AWS, Google Cloud, Herkou, etc.), and 
  • Communication protocols (MQTT, CoAP, XMPP, and likewise).

Step 4: Development and Testing

In this step, the prototype app is put to development and testing. Like all other application, website, and software development cycles, this phase is divided into front-end and back-end

JavaScript is arguably the most widely used language for creating front-end apps. Various frameworks, such as Angular, React, and Vue, leverage the power of JS to make the software development process easier and more enjoyable for developers. Ultimately, the best framework for any project depends on the individual’s experience, preferences, and requirements.

Back-end development requires a more intricate selection of tools, as each component needs to be compatible with the other. If a JavaScript-based front-end layer is desired, then Node.js would be the natural choice for back-end programming as both are JavaScript-based. Preferred JS database options are CrateDB, InfluxDB, MongoDB, RethinkDB, and SQLite; DevOps tools can be Gradie, Jenkins, and Docker.

Once development is complete, the application must be tested (automatedly or manually) to ensure that there are no bugs and that it satisfies the desired user experience requirements.

Step 5: Deployment and Maintenance

Once tested and verified, the app can be deployed to its intended platform (cloud platforms), with ongoing maintenance and support provided. Regular monitoring should be conducted to guarantee that the application remains bug-free and keeps functioning as intended.

Mobile vs. Web IoT Apps: Which would suit you the best?

It all depends on what you’re trying to achieve – do you want a simple app that allows you to connect and perform daily functionalities, or do you want to create something more complex? 

If you’re looking for something convenient, Mobile IoT Apps are likely the best choice. They are accessible on the go and allow you to interact with connected devices quickly. Plus, with many of them being built with HTML5, you can create rich, easily updated, and maintain applications. 

On the other hand, if you need something more powerful and feature-rich, then Web IoT Apps might be the way to go. With a web-based application platform, you can avail of complex applications with a wide range of features and functionality, such as powerful analytics and data visualization. Plus, you can access these applications from anywhere with an internet connection, making it perfect for those who want to stay connected.
