Ultimate To-Do List to Launch a Successful IoT Project

IoT Project Development Process

First of all, behind any successful IoT project, there is always a brilliant idea upheld by the market demand. Your product may be a truly ingenious invention but if people do not need it, the solution is doomed to failure.

Once you have a great idea, the next big step is to define the goals and elaborate a business strategy that lies behind your Internet of Things project development. Then, you can move to its technical implementation.

Depending on the needs your solution is going to address, its complexity may vary, and thus your IoT project plan and scope of work may be different as well. However, there’s a list of steps we provide below that can be found across the development journey of IoT products for various business sectors and objectives.

Generally, the IoT ecosystem includes three core blocks — hardware, software, and connectivity. Thus, the high-level checklist to deliver a full-fledged IoT solution includes but is not limited to:

• Analyzing requirements
• Engineering hardware
• Implementing edge gateways
• Designing the IoT cloud
• Providing fleet management capabilities
• Developing the backend
• Delivering web and mobile applications
• Ensuring all components’ connectivity
• Complying with core regulations
• Getting your product certified

IoT Project Infrastructure

As you may see from the previous part, IoT projects are more than just the development of connected devices and also include the creation of an entire IoT infrastructure.

Based on our experience, we came up with the six key components that any viable IoT infrastructure should contain: IoT Device, Mobile Application, Backend, eCommerce CMS, CRM, and Accounting Solution.

The hidden traps and pitfalls are inevitable when carrying out an IoT project. Working on the development of the IoT product, we encountered different technical problems almost at every stage.

In this part, we are going to retell you about how we coped with these difficulties, being convinced that our experience will be of significant value for launching a truly successful IoT project.

IoT Device

A smart device or an IoT device is the key component of any IoT project. It is primarily used to detect events or changes in the surrounding environment and transmit the aggregated data for analysis.

IoT devices vary a lot depending on their purpose. But irrespective of their type, to ensure the effective functioning of the entire IoT system, they should all comply with a number of established requirements.

The main objectives of IoT device development are:

• Low power consumption;
• Stable operation;
• Optimal use of communication technologies: BLE, Bluetooth, GPRS, 3G, LTE, Wi-Fi, NFC, RFID, etc.;
• High-quality components;
• Compact size;
• Optimal prime cost;
• Regulatory compliance.

In our platform, we laid the possibility of processing data received from various sensors embedded in IoT devices. Among them, one can find cameras, microphones, accelerometers, as well as sensors for tracking temperature, humidity, location, lighting, motion, and health indicators.

In cases where IoT devices send small amounts of data at a time, their design is rather simple. Difficulties, however, may arise when there is a need to transmit large volumes of information or when there are certain regulations and security restrictions.

Our team faced these difficulties when working on a wearable device and an application for one of our clients. The sensors, that we used in the project, such as cameras and microphones, were supposed to transmit large volumes of data on a regular basis.

Initially, we considered using BLE as a data transmission channel. But since the speed provided by it was insufficient, we opted for Classic Bluetooth.

At that moment, we encountered another problem. For a device to work in connection with an iPod, iPhone, or iPad, it has to undergo the MFi certification. This is a strict rule set by Apple, which examines products and even their packaging for compliance with statutory requirements.

The efforts of both the manufacturer and iOS app developer are essential for the successful completion of the MFi licensing program. This is why we assisted our client with the collection of all the necessary documentation, helping to get the MFi member status and release the product in a short period of time.

Mobile App

Smartphones have become an integral part of our everyday life with their performance and capabilities coming close to those of PCs. By delegating some PC tasks to smartphones, we can significantly reduce the BOM cost of an IoT electronic device and simplify the interaction with users.

IoT Mobile Apps Are Used For:

• Receiving data from sensor devices and transmitting it to the backend;
• Processing, analyzing, and storing historical data;
• Displaying the real-time data from smart devices and user’s account information;
• Setting up and configuring connected devices.

Moreover, by taking advantage of all mobile platform features, we can add value to the user experience and greatly extend the solution’s functionality. With these capabilities, mobile app development has become an essential component of many IoT projects.

To be considered in the process of mobile app development:

Many IoT projects require the transfer of large amounts of information from sensor devices in real time and over the course of a long period. In cases where such data is transmitted for analysis via smartphone, it leads to a rapid battery drain. This makes crucial the task of power usage optimization. The goal is to find a balance between the data transmission speed and the smartphone’s battery usage to enable quick but stable operation of an IoT system.

At the same time, it is important to maintain the stability and speed of information transfer from a device to a smartphone. You need to carefully design an algorithm to be employed for interaction between an application and a connected device. Among others, it has to spell out the IoT system’s responses to such irregularities as a loss of connection, data transfer errors, and corrupted data detection.

Backend

The backend development is one of the most demanding and responsible phases of building an IoT system. The logic of data storage, processing, and presentation is formed at this stage.

Once your connected devices have collected the information about the surrounding environment and have passed it via smartphone to the cloud, it has to be properly stored, analyzed, and visualized. That is the backend or server side of your IoT solution that is responsible for performing the mentioned tasks.

Making the collected data valuable for the end user, the backend constitutes the central link between all parts of the IoT system.

Backend Requirements:

• Scalability and high performance;
• Integration with custom electronic accessories or mobile apps;
• Third-party systems integration;
• Advanced UI and data visualization;
• Triggering activities based on deep learning algorithms;
• High availability;
• DDoS/hackers attack protection and data encryption.

The scalability of an IoT platform is one of the key challenges faced during its development. It is highly important to ensure the sustainable operation of the system. If the number of users increases, new servers have to automatically get involved in the processing of users’ requests.

At the same time, when the load decreases, idle servers have to disconnect from the process to avoid wasting resources. To solve the scalability problem and ensure the appropriate distribution of the load on the servers, we used RightScale and AWS Load Balancer.

The choice of technologies is a question that has to be approached carefully in the process of backend development.

When creating our IoT platform, we estimated the benefits and capabilities of both open-source and proprietary solutions. In the end, the preference was given predominantly to open source technologies such as Linux, Node.js, and MongoDB. There were several decisive factors behind our choice, including the high reliability and security of open-source solutions and their relatively low cost in comparison to vendor-exclusive technologies.

eСommerce Solution

To allow users not only to learn about your project but also to buy devices and subscribe to services, you need to have a convenient and functional website. The choice for a particular eCommerce solution should be based on the objectives of your IoT project and the technical qualifications of your developers.

Our team has been previously involved in many eCommerce projects. For most of them, the OpenCart CMS happened to be the best choice. It is a perfect solution for small budgets and tight deadlines, as there is a great number of ready-made templates and integration modules in free access.

At the same time, this eCommerce CMS product can be easily scaled along with the growing number of customers, thus enabling the design of a flexible and functional IoT system.

An additional advantage of OpenCart is that it can be easily integrated with various credit card processing and payment services. To fully meet the needs of our client and enable the execution of eCommerce transactions, we decided to use WorldPay, formerly Vantiv. As there was no integration module for this specific payment system, we developed one by ourselves.

From our own experience, we learned that the integration of OpenCart with billing services is a relatively simple task that can be carried out in the short term.

Nevertheless, there are some nuances of working with OpenCart: occasionally, bugs and critical vulnerabilities can be found in the CMS. In the newer versions of the platform, these problems are usually fixed, but an automatic upgrade may lead to the loss of custom changes.

This is true for almost all ready-made solutions and has to be taken into account already at the project’s planning stage. When it comes to OpenCart, instead of directly modifying the core files, use a tool like vQmod. It will help you avoid problems with the system and minimize the costs of its upgrade.

CRM

The implementation of a CRM solution is the next important step in designing an IoT platform. The choice for a particular CRM should be based on your company’s specific business processes, as well as the size of the client base and the preferred type of interaction with customers.

For our IoT platform, we used Creatio CRM. Its open configuration and extensive API enable the smooth integration with other components of an IoT system and the accurate synchronization of data among them.

The Creatio solution also allows for conveniently aligning business processes and omnichannel communications, including integrated telephony. Easy to scale and configure, this CRM is an indispensable tool for building a reliable and powerful IoT platform.

Accounting

Regardless of your monetization strategy, you will need an accounting solution. At the initial stage of your business development, when the turnover is still relatively small, it is possible to use third-party accounting software. But over time the number of users will grow and the export of data into your accounting system will turn into tedious work, taking up too much effort.

The integration of an accounting solution with an IoT platform can easily solve this issue. It significantly simplifies bookkeeping, as the accounting information is automatically uploaded to the system when a person makes a purchase or subscribes to services.

Working on this part of the project, we came to the conclusion that the most convenient way is to use a ready-made accounting solution. We opted for the QuickBooks accounting software package.

For businesses requiring more tailored features or deeper IoT integration, our custom accounting software development services can provide scalable solutions that align perfectly with your platform and workflow needs.
