Anatomy of an IoT System

It’s a good idea to accept the components of IoT solutions and how they interact before diving into the specifics of IoT app development. A typical IoT system has four major components in general.

Anatomy of an IoT System
Figure 11: Anatomy of an IoT System

Sensors and Devices (Hardware)

The input device or sensor is the initial component of an IoT system (s). Sensors gather information such as temperature and video or audio feeds.

A gadget usually has a collection of sensors that collect and share data from its surroundings. A smartphone, for example, is a device with several sensors such as GPS, accelerometer, microphone, camera, and so on.

Cloud Connectivity (Networks)

After the data has been acquired, it must be shared and stored with the cloud infrastructure. Therefore, the IoT system utilizes a data transport network such as Wi-Fi, satellite, cellular, wide-area networks (WAN), and various other options.

Each network has its benefits, such as reduced power usage or higher bandwidth. Before choosing which network to utilize, you must decide which qualities are most relevant to your system and intended output.

Data Processing (Software)

When data reaches the cloud, it is processed by a software program that collects, analyzes, and prepares it usable.

A smart heater in your house, for example, will gather temperature data and send it to the cloud, and the software will evaluate it to determine if it’s warm enough or too hot. The data is then relayed to the user or utilized to operate the heater.

User Interface (App)

Once the analytic engine has been analyzed, the data is synchronized with a user interface, generally a mobile app.

Frequently, there will be a user dashboard that allows individuals to see data clearly and concisely at a glance. When detailed data is acquired, the app can also inform users. For example, if an attacker enters a home equipped with an IoT security system, a motion sensor activates an alarm and sends a text message to the homeowner. After that, the user may launch the app and watch live video footage from their house over the cloud.

Considering Factors for IoT App Development

Between expected exponential growth and a growing desire for IoT solutions, it’s apparent that IoT innovation and IoT app development will be critical to corporate success over the next decade.

Integrating IoT devices requires strong, well-designed, and dependable IoT software, as users will only buy the device if the app is up to par. So let’s look at some of the most important variables (apart from UI/UX) that will influence the success of your IoT app.

Considering Factors for IoT App Development
Figure 12: Considering Factors for IoT App Development

Plug Security Gaps

One of the major issues with IoT systems is the absence of standard security procedures. Due to a lack of security, IoT systems are vulnerable to hacking and cyber assaults such as DDoS attacks. For example, the Dyn cyberattacks of 2016 targeted IoT technologies such as printers, cameras, baby monitors, and other devices with malware used to carry out the assaults, causing widespread disruption.

The only approach to keep hackers and cybercriminals from abusing the inherent weaknesses of IoT is to create apps that fill in the gaps and secure data transit. Many IoT app developers already include communication layer security protocols such as TLS or DTLS in their apps. There have also been significant advancements in blockchain technology to encrypt data in IoT apps. 

AI Data Analysis

An IoT system’s core workflow consists of five steps: produce, communicate, aggregate, analyze, and act. First, the sensors exchange data over an aggregated (collected) network on the cloud. The following stage is data analysis, carried out by an IoT app and maybe augmented using AI and machine learning technologies.

By incorporating an AI engine or machine learning algorithms into an IoT app, device developers may obtain data insights rather than simply raw data. The information gleaned from the data may then be utilized to enhance workflows.

For example, robotic arms can be equipped with IoT sensors that transmit data to an IoT app on a factory assembly line. For example, the AI can read and analyze the data to identify locations where production slows or where energy efficiency should be improved. The information gained can then be utilized to improve assembly line operations.

Opportunities for Business

Investing in bespoke IoT application development opens up the following business opportunities: 

  • Automation of company operations and services; 
  • Enhanced productivity; 
  • More productive remote working; 
  • Fast response to changing conditions; 
  • Cost savings.

IoT solutions should not be viewed as a one-time investment to tackle technological problems. Instead, they may evolve into a distinct ecosystem capable of managing various processes and workflows.

Consider a company that produces machine-milled parts for the automotive sector. They may obtain real-time notifications of any machine faults or failures by establishing an IoT app that connects with their assembly line and CNC machine sensors. This enables them to respond to problems more rapidly, correct them, and resume production. It may also assist in automating time-consuming operations, such as quality checks, which can be done using IoT sensors and AI instead of optical inspection.

Create A Continuous User Experience

Creating a bespoke IoT app allows you to use the agile Continuous User Experience approach (CUE).

CUE entails gathering information and data from anybody who utilizes your app. You may examine all of this information to see how users engage with it. This makes your app more user-friendly by allowing you to adapt and tweak it depending on user requests. By optimizing your app, you may increase consumer loyalty and get an advantage over your competition.

Java is a great programming language for desktop programs, but it can also be used to create embedded systems. Embedded systems developers highly recommend Java applications due to their reliability and the availability of several development tools. Embedded system programs written in Java are easily transferable across different IoT platforms. 

Developers may use Java to separate the critical parts of embedded programs from the rest of the code. Furthermore, Java programs are quick and may execute smoothly even on older hardware.


Rust is a contemporary programming language that may be used to create embedded devices. It is an excellent choice for embedded systems because of its higher-level notions, assured safety, typestate programming style, and zero-cost abstractions. Its sophisticated static analytics ensures that unneeded application components do not use system resources. 

The concurrency paradigm in Rust assures that no two threads may share the same state at the same time. Developers may easily include Rust into their C++ or C projects. Whether programming SBCs or small microcontrollers, Rust allows you to port your integrated system’s code between platforms.


Python has gained traction as the top embedded systems programming language in recent years after gaining acceptance in the online and corporate worlds. Python is the best choice for embedded systems for beginning developers because of its accessible and simple writing style. Python programs will require a Python runtime because it is an interpreted language.

However, it’s the most effective way to write real-time embedded system automation tests. Python excels in developing embedded systems for processing data in real-time due to its ease of processing pictures and parsing logs.

Step-by-Step Process of IoT App Development

Developing an IoT application is influenced by various factors, including the organization’s budget and overall timetable. However, the followings are a few of the most typical stages and considerations:

Step by Step Process of IoT App Development
Figure 14: Step-by-Step Process of IoT App Development

Hold the Initial Project Planning Meeting

The project’s aims and objectives are hammered out during the planning phase. During this point, the questions answered should balance the firm’s demands, such as budget and deadline, with those of the app’s customers, such as functionality and simplicity of use.

Select the app development platform

Organizations can pick from a range of platforms, including no-code and low-code. Developers choose different platforms to link items into a single system. Google’s IoT platform, for example, enables low-energy sensors and other manufacturers’ goods.

Choose the Hardware

If IoT app developers don’t want to construct their hardware, they should look for a reliable provider to undertake the task. Two primary issues for ensuring the application operates as intended are reliability and connection.

Begin the Design Phase

When it comes to the design process, developers should put speed and performance first. Many Internet of Things (IoT) apps capture data in real-time. Therefore, even a few seconds’ latencies may be too long for some applications. Security must also be a major priority during the design process since this will lower the likelihood of difficulties later.

IoT App UX/UI Design

Customer-facing components, such as a mobile app and a web interface for displaying data from linked devices, should be prioritized when developing IoT apps.

As you may recall, I indicated that certain ready-made IoT platforms provide critical building blocks for developing customer-facing apps. Even if this is the case, keep in mind that you must validate your UI/UX assumptions with clients via interactive prototypes before solidifying these user experiences.

You may safely use the default UI for an admin portal because it will be controlled internally by your staff.

IoT App Coding

Once your app developers start putting together lines of code to construct IoT apps, ask them whether they intend to leverage any third-party SDKs and APIs to speed up the process. On the market, there are a plethora of frameworks and pluggable components for developing mobile and online apps.

Prioritizing the creation of a back end, and in particular, APIs pays dividends since mobile application development may proceed at a constant rate, with no hiccups, alongside online development.

Test the Prototype of the IoT App

Prototyping is an important component of IoT app development. It demonstrates real-world viability and allows companies to sort out any difficulties before releasing the app. Developers can also check compatibility concerns between different vendor goods and software.

Tweak the Design Based on Testing

Even the most well-considered designs will almost certainly require revisions following testing. These are not an indication of a deficiency on the part of the development team but rather a reflection of the fact that problems frequently occur when consumers use the software. Testers frequently engage with the app in ways that the developers had not anticipated.

Delivery and Maintains of the IoT App

I’m sure you’re well aware that once your app is published, you can’t sit back and relax. Aside from marketing, you’ll be busy processing consumer feedback, which you’ll hopefully transform into new features or small interface changes.

The IT team will need to maintain track of modifications to the product’s frameworks and keep an eye on new mobile OS releases for opportunities to improve user experience.

Once your product is up, there is more work to be done because you will be serving paying consumers. And if you keep improving your software, they’ll probably remain around long enough to sponsor another major update.

The Cost of Developing an IoT Application

The development of different digital products follows a similar pattern. First, you must determine your startup’s overall concept. Following that, the market research and budgeting steps take place. Because accurate cost estimation is critical to your project’s economic success, we’d like to summarize the effect of IoT application development in 2020 briefly. The technological complexity of IoT items distinguishes them from all other products.

The Cost of Developing an IoT Application
Figure 15: The Cost of Developing an IoT Application

Applications and gadgets for the Internet of Things may be found in practically every area of our life. According to statistics, $235 billion was invested in 2016 alone, a 22% rise over 2015, and 2017 was the explosion year. The Internet of Things (IoT) industry is extremely promising, and significant funds have been spent.

Building an IoT product necessitates using an IoT network and middleware in your bespoke digital infrastructure. The sort of application and its level of difficulty may also differ. A simple IoT app includes a restricted number of device connection choices and just the most basic functionality to present data. The budget for general development might begin at around $30,000.

APIs, GPS tracking, payments, and other smart device connections might result in a complex IoT app with many sophisticated features. This might include sync, third-party API integration, and security tool integration. A minimum of $50,000 should be budgeted for product development.

Cost of Maintaining

The hourly wages of programmers are also important. Outsourcing development remains the most cost-effective choice since it allows you to select professionals from a worldwide labor pool. At the same time, consider whether outsourcing (offshore or nearshore) risks incomplete or partial project failure as a separate factor. In 2020, the number one outsourcing destination for European and US startups in Eastern Europe will charge an average of $50 per hour. For example, North American developers charge over $150 per hour, whereas Western European enterprises charge around $100 per hour.


IoT app development is necessary for a basic approach, extensive understanding of hardware and software technologies, and effective skills. However, suppose you have a concept for an IoT application. In that case, our team of IoT professionals can assist you at every level of the process, from cost assessment to post-delivery assistance.

So, it has been determined that the Internet of Things is well-suited for making substantial changes to the traditional app development process. Using IoT, enterprise mobile apps may improve the efficiency and productivity of a time-consuming business process.

Furthermore, you may control the entire IoT network from your office area. If App Development Firms can do it right, the future of IoT app development will undoubtedly bring greater solutions.
