Today, the Internet of Things (IoT) has found applications in numerous fields like smart homes (home automation), medical & healthcare, environmental monitoring, agriculture, manufacturing, energy management, and old-age care, among other things.
IoT functions on a simple concept – multiple devices are connected to one another, thereby forming a network of devices connected via RFID (Radio Frequency Identification) system along with routers, actuators, and sensors (motion sensors, temperature sensors, moisture sensors, light sensors, etc.).
In-demand Machine Learning Skills
These devices share data among themselves to provide more control and convenience to consumers to operate them. According to Statista, by the end of 2018, nearly 22 billion IoT devices were estimated to be functioning across the globe. By 2030, the number of IoT and connected devices will grow to 50 billion!
As both businesses and consumers continue to adopt smart devices and IoT solutions, it gives rise to a pertinent challenge in the industry – finding professionals with the right talent and skills to handle the diverse job roles in the IoT domain. According to the Talent Supply Index (TSI) report by Belong, “the demand for IoT talent rocketed by 304%, between 2014 and 2017.” Presently, this trend shows no signs of slowing down.
One such challenging (and promising) IoT job role is that of an IoT Developer.
Who is an IoT Engineer?
The role of an IoT Developer/Engineer is a broad umbrella that brings to play multiple disciplines and skillsets. IoT Developers are professionals who can develop, manage, and monitor IoT devices and systems by combining three core components – data, technology, and research.
Since this is a versatile role, IoT Developers must be well-versed in diverse areas, including security, networking, systems engineering, cloud programming, and hardware device programming. This imparts a degree of flexibility to IoT Developers and allows them to wear multiple hats simultaneously.

How to become an IoT Engineer?
To become a successful IoT Developer, you must first build a strong foundation in the following:
1. Understand the nitty-gritty of sensors
Like we said earlier, IoT primarily revolves around sensors, and hence, every IoT Developer must have an in-depth understanding of sensors. It is sensors that gather and forward the data in an IoT network. You must get familiar with the mechanism of different kinds of sensors and also study their architecture.
It is crucial to have a sound understanding of wireless communication systems and embedded logic to understand the unique triggers and functionalities of different components.
2. Pay close attention to UI
User Interface (UI) and User Experience (UX) are the two pillars of success for any application, and IoT applications are no exception. Since consumers rely on IoT solutions to make their daily lives more convenient and comfortable, you cannot compromise on the UX. And UX can only be top-notch when the UI is lucid, fluid, easily navigable, and optimized for multiple platforms.

4. Get handsy with Raspberry Pi
While reputed organizations like IEEE believe that IoT Developers must hail from Computer Science or Electrical Engineering backgrounds, solutions like Raspberry Pi are helping change this norm. Using Raspberry Pi to design and develop small IoT projects, you can demonstrate your skills and aptitude to potential employers.
Essentially a Raspberry Pi is an inexpensive, tiny computer that is mostly used in the proof-of-concept IoT projects. It allows you to patch together simple circuits and then connect those circuits with software. By creating such simple projects, you can show that you have the requisite know-how and the push to take such initiatives for building IoT projects.
5. Focus on “Mobile”
Mobile devices like smartphones and smartwatches have witnessed an exponential growth curve, thanks to their increasing adoption around the world. Since mobile devices are the most preferred and popular technology (thanks to their mobility and convenience factors), you must acquire skills related to mobile technology. This will help you to optimize your IoT apps and solutions for mobile platforms, thereby giving you a more expansive user base.
IoT Engineer / Developer Salary in India
The IoT Developer salary in India depends on several pivotal factors like the size and reputation of the company, the job role, location, and the educational qualification, skill set, and work experience of the candidate. However, rest assured, IoT Developers earn more than decent yearly remuneration.
The IoT India Salary Study 2017 maintains that the salary of IoT professionals in India is nearly 76% higher than that of IT professionals. While IoT professionals get a median salary of Rs. 15.2 LPA, the median salary of IT professionals is around RS. 8.65 LPA.
The considerable salary difference between IoT and It professionals is because IoT is a relatively new field, which means that there are not enough talented and skilled professionals in the IoT domain. As a result, IoT professionals demand much higher salaries in return for their skills and experience.
While freshers in the IoT field earn yearly salary packages ranging between Rs. 3.5 – 6 LPA, mid-level professionals can make as much as Rs. 10-25 LPA, denoting over 50% jump in the salary scale.
