The Internet of Things (IoT), which is used in many fields today, includes smart homes (home automation), healthcare, environmental monitoring and long-term care. The demand for IoT engineers is increasing.
IoT is based on a simple principle: Multiple devices are connected to each other, creating a network of devices via RFID (Radio Frequency identification) systems, routers and actuators. These devices share data between themselves to provide consumers with greater control and convenience in operating them.
Let’s take a look at the steps you need to become an IoT engineer.
About IoT developer/engineer
The Microsoft Azure IoT Engineer/ Developer exam AZ-220 is responsible for the implementation of coding and management of IoT solutions’ cloud and edge components. The IoT Developer configures and maintains devices using cloud services, but also sets up physical devices. The IoT Developer is also responsible for maintaining devices throughout their lifetime.
These are the prerequisites for passing the AZ-220 Azure certification test:
For developing an IoT solution, you need to have a thorough understanding of Azure service implementation.
Ability to recognize Azure IoT service configuration settings within an IoT solution’s source code.
Ability to code specific IoT tasks in at least one Azure supported programming language such as Python, C# C, or Node.
Let’s now get to the main point.
How can I become an Azure IoT Engineer?
An IoT engineer is a broad role that covers a range of skills and disciplines. IoT developer/ Engineer is a specialist who can create, manage and monitor IoT devices. This involves combining three key elements: technology, data, and research. Let’s start thinking about how we can get started in this field.
Step 1: Get to know the exam syllabus in detail
