How to become an IoT Developer

Firstly, what Is the Internet of Things (IoT)?

The Internet of Things (IoT) has recently become one of the trendings and demanded technologies. The IoT is a giant ecosystem consisting of internet-connected smart devices, using integrated systems, such as processors, sensors, and communication equipment, to collect, send and process data from the environment.

According to the IoT market, in 2022 IoT devices are expected to grow by 18% to 14.4 billion active connections and by 2025, there are anticipated to be around 27 billion. 

So, what about IoT engineering and its role? The IoT engineers are high-level professionals who build and construct various devices, sensors, and software, allowing devices to connect with other systems or devices effortlessly.

Engineers in IoT are responsible for the software, hardware, and networks, starting from Big Data to Blockchain and AI, from Cybersecurity to UI design, and ending with communication protocols: they research, build, test, and document IoT solutions with embedded systems and devices.

The IoT engineering also includes work throughout the IoT architecture: from devices to the cloud, user interfaces, connectivity, and support – the backbone of the system. 

What Skills are Required for an IoT Developer? 

Engineers in IoT apply solutions to any network and platform connectivity issues and even work as service designers, analyzing user needs. In the IoT industry, the dominant and most used programming languages are C and Java, then come C++, JS, Python, Swift, etc. 

They develop and operate a large variety of IoT devices and systems through the combination of 3 main elements: technology, data, and research.

How to be an IoT developer? If you have decided to start your career in this field, then here you can find the must-have skills required for becoming an IoT developer:

  1. Learn JS – an effective event-based language for reacting to new data from devices
  2. Learn Python one of the most fast-growing and flexible languages, supported by large storage of libraries 
  3. Deeply understand sensors and hardware – how they work and how to embed them into the system infrastructure, layers of architecture, 
  4. Experiment with Raspberry Pi the best tool, that can be used without having a background in computer science or electrical engineering
  5. Cloud – Data Storage as soon as the data enters the cloud, the software determines what action needs to be taken. IoT sensor/device interacts with the cloud through the connection, either physical or wireless
  6. Solid Security IoT devices collect big data, so should be strongly secured and protected
  7. Customer-focused approach – meet the highest quality standards in terms of user experience and ensure that products are easier and faster to use, even for those who are not tech-savvy

Being an IoT developer is not just constructing a device and quickly passing it to other specialists to finish the work, but it is the detailed understanding, analyzing, architecting, building, designing, and only then testing and keep testing, improving, and developing until it works perfectly.
