IoT Application Development [ How to Develop an IoT App? ]

IoT (Internet of Things) is an imminent technology. In recent times, plenty of sectors are relying more on internet-connected devices.

There is a growth of IoT technology and the development of more devices, sensors, and gateways. So, there is an increasing demand for efficient apps and software that can fully integrate with the IoT system.

Basically, the IoT application development intends to infer the incoming data, scrutinize it, and then present it in a user-friendly approach. But the increasing demand for IoT proficiency has made it more difficult for many organizations to seal the skills gap and recruit outside experts.

And the corresponding demand also resulted in an increase in the implementation of no-code as well as low-code development platforms for the IoT apps. With the help of IoT app development, a lot of organizations chose to develop an IoT app internally.

Now let’s go through the in-depth details of the Internet of Things and how to create an IoT app with this ultimate guide.

So without further ado, let’s get started…

What is the Internet of Things (IoT)?

What is the Internet of Things IoT

The Internet of Things (IoT) represents any equipment or device which connects to the Internet with the help of embedded software. The implementation of IoT technology to a device makes it more intelligent. The reason is it facilitates digital data communication with other systems and devices, in real-time.

Consequently, it leads to an opportunity to incorporate valuable features to devices as well as optimize operations and processes. In other words, IoT relates to the interlinking of appliances, digital devices, machines, people, and other objects with each other through wireless networks.

IoT Application Development is the procedure of developing IoT applications as well as products that can be remotely controlled. This process can prove useful to supervise the environment or condition of the connected product through external data sources and sensors. To fulfill the direct requirements of any business, Custom IoT Development is used.

Basically in this type of development, cloud-based software as a service ( SaaS ) apps are used. They present a bridge between the Internet and IoT devices. Thus, they facilitate the assimilation, inspection, and analysis of data produced by the hardware.

How to Develop an Internet of Things (IoT) Application

For the development of an IoT application, there are 4 key aspects Hardware, Networks, Software, and Apps which play a vital role. Talking about the process, the analog signals captured by sensors are sent to the cloud or specific interface for processing. The software then processes the data after it reaches the cloud. Subsequently, an individual uses the interface of a particular IoT app to receive, communicate and customize data.

Moreover, there are 5 major IoT app development platforms:-

Now let’s get thorough details of how to develop an IoT application by understanding the anatomy of the system, factors to consider during the development process, and stages.

Anatomy Of An IoT System

Anatomy or Working of an IoT system and how all components are involved in IoT solutions and the way they are interconnected. Below we have given a quick overview of all 4 key components which are the basics of any standard IoT system.

  • Sensors and Devices (Hardware): Sensors amass relevant data like audio or video or temperature. Typically, a device contains a group of sensors that assimilate and share data from the neighboring environment.
  • Cloud Connectivity (Networks): After the data has been gathered, the subsequent step is to share the same with the cloud infrastructure and save it. For this, the IoT system utilizes a data transport network like cellular, Wi-Fi, satellite, WAN (wide-area networks) etc.
  • Data Processing (Software): After the data approaches the cloud, it is being processed through a software program. The purpose behind this is to collect the data, examine it, and present it in a practical format.
  • User Interface (App): After the data processing through the analytic engine gets completed, it is synchronized with some type of user interface. Typically, the mobile app is preferred with a user dashboard that enables people to view the data. Moreover, the app can inform people when certain data is amassed.

Now let’s move to the factors to consider…

Factors to Consider During IoT Application Development

Factors to Consider During IoT Application Development

In the above section, we discussed the anatomy of an IoT system but here we will talk about the key factors that should be considered and are responsible for the success of IoT applications.

1. Plug Security Gaps

One of the key issues faced in IoT systems is that these systems are deficient in familiar security protocols. Due to the deficiency of security, the IoT systems are vulnerable to hacking and cyber attacks like DDoS attacks. It is known that the Dyn cyberattacks of 2016 negatively influenced IoT technology like webcams, printers, baby monitors, and many other devices with malware. The most effective way to avoid cybercriminals and hackers from abusing the inbuilt vulnerabilities of IoT is to create apps that close the gaps and defend the transfer of data.

2. AI Data Analysis

The fundamental workflow of an IoT system involves five steps, namely, create, communicate, aggregate, analyze, and act. Firstly, the sensors establish data communication via a network that is amassed in the cloud. The subsequent stage is data analysis that is carried out by an IoT app. It can be improved with AI and Machine Learning technology.

3. Opportunities For Business

The investment in custom IoT application development gives rise to various business opportunities. And here is the list of these opportunities:-

  • Productivity optimization
  • Automation of business services and processes
  • Allow more productive remote working
  • Enhanced data sharing across businesses
  • Quick response to changing circumstances
  • Facilitates cost reductions

4. Creating a Continuous User Experience

With the development of a custom IoT app, you can adopt the agile method of Continuous User Experience (CUE). Continuous User Experience (CUE) entails obtaining information and data from anyone that uses your app. Moreover, you can scrutinize all the relevant data and precisely know how the user interrelates with the data. Consequently, it improves your app depending on user queries. This also leads to making it more user-friendly. The app optimization performed this way enables you to create customer loyalty and beat your competitors.

Till now we have discussed the IoT platforms, anatomy, and factors to consider. Now let’s move to the development stages.

IoT Application Development Stages

IoT Application Development Stages

The process of creating an app for its integration with an IoT ecosystem demands meticulous planning and design. And for the successful creation of app through IoT system, it is advisable to consider the 5 Software Development Life Cycle (SDLC) Stages discussed below:-

1. Planning the Framework of Your App

Firstly, you need to work on planning the overall framework of the IoT app. You need to determine what features would be required, the way UX would work, the way the app would interface with the system software of the device, and the proper way to perform data transfer between the IoT app and devices.
