A professor at the Pohang University of Science and Technology in South Korea teaches this free course, and a certificate is awarded upon completion.

3. EdX's Introduction to the Internet of Things

This course presents the fundamental concepts of IoT. It covers the different components that make up an IoT system and how they are connected. EdX's course gets into IoT's benefits and the many cybersecurity and privacy issues that surround it. Once done, students have a basic idea of how to implement IoT in their field.

Professors at Curtin University in Australia teach this free course. However, there is a $149 fee for a verified certificate of completion.

4. Simplilearn's Introduction to IoT Training Course

This introductory course covers everything from IoT origins and IoT fundamentals to IoT designs, frameworks, development considerations and using IoT in the enterprise. The course is geared towards mid-level to CXO-level management professionals who want to use IoT to grow their business.

The $399 course has no prerequisites. A certificate is awarded upon completing the course and getting at least 80% on the exam.

Intermediate online IoT courses

IT pros who are acquainted with IoT or who have worked with simple IoT devices might be ready for one of many more advanced offerings, such as the following courses:

IoT is booming and is expected to stay that way for years, making it a solid career option.

1. Coursera's Architecting Smart IoT Devices

IoT systems and the smart home and industrial devices they work with are made up of many integrated IoT software and hardware components. This course teaches students about these components, including networks, boards, OSes and processors. But most importantly, it provides best practices on how to integrate components. At the end of the course, students should be able to architect an embedded IoT device. EIT Digital offers this free course and awards a certificate.

2. Coursera's M2M and IoT Interface Design and Protocols for Embedded Systems

This course focuses on connecting devices to one another and to the cloud to create prototypes and real-world systems. It introduces machine-to-machine (M2M) and IoT concepts and covers using AWS to develop IoT systems and the communication protocols involved. It also includes IoT design strategies, such as message queuing, interdevice communication, security, APIs and microservices. The free course is taught by the University of Colorado Boulder.

3. EdX's AWS IoT: Developing and Deploying an Internet of Things

This course covers everything that's needed to build cloud-based IoT applications on AWS. It introduces AWS IoT and then delves into topics such as device management, device gateway, device registry and shadows. It also discusses IoT security risks and AWS security features. Students learn how to integrate IoT systems with analytical tools.

AWS technical trainers teach the course. A free version is available, as well as a $99 version where students receive a certificate upon completion. Students are expected to have at least a year of software development experience and a basic understanding of AWS and its console.

4. Udemy's Raspberry Pi and Arduino -- Go to The Next Level

This course teaches students to make Raspberry Pi and Arduino communicate and guides them through hands-on, custom projects. It shows students how to create serial communication between the two devices and build an application based on that connection.

The course is for students already familiar with Arduino and Raspberry Pi and have a basic understanding of Python and C++ programming. They will also need access to both boards. By the end of the class, students will have created their own Raspberry Pi-based camera and Telegram bot, and have created an intercom system using the two boards in the final project. Course price may vary.

Handling IoT security challenges
Security is a major issue for IoT systems. Advanced IoT courses cover mitigation strategies for many of the vulnerabilities they face.

Advanced online IoT courses

IoT experts can take their pick from a range of courses to expand on your knowledge, including the following:

1. Cognixia's Internet of Things Security Expert Training

Connecting things to the internet is no longer hard. It requires a few sensors and programmable boards. However, securing these systems is challenging. This course is for experts who want to focus on security. Students learn to build, test and deploy Python-based IoT applications. The course also covers cryptographic techniques to secure IoT applications and networks. Students gain expert-level knowledge of designing and building scalable IoT ecosystems.

Students should know programming and IoT fundamentals, as well as some statistics, to take this $1,200 course.

2. Coursera's Internet of Things Capstone V2: Build a Mobile Surveillance System

This course teaches students to design and build an IoT system that uses at least one communication protocol, one actuator and two sensors. Students learn to use mobile platforms to develop systems that connect actuators and sensors to the Arrow Electronics' DragonBoard 410c development board and gain enough programming experience to create a fully functional system.

The University of California, San Diego, offers the free certificate course. Prospective students should have intermediate level knowledge of IoT and board and software programming.

3. RWTH International Academy's Certificate Course 5G Communication and the Internet of Things

IoT devices require fast, dependable communication technology such as 5G networks. This course covers various 5G topics and technologies relevant to IoT, including system design, long-term evolution system optimizations, sensor signal processing, radio frequency systems, algorithmic AI, and IoT board developments. Pricing and other details about this course are available directly from RWTH.
