The Internet of Things (IoT) is a business enabler. IoT is replacing inefficient manual processes by remote controlled and automated solutions which are less sensitive to errors. Popular application areas are connected cars, predictive maintenance (esp. for machines) or smart meters (for energy consumption).

But IoT is everywhere, and business opportunities are unlimited. In fact, cellular networks or LEO satellites are providing ubiquitous availability of IoT connectivity at reasonable cost. This foundation enables new IoT use cases, fuels innovation and inspires the industry to develop tailored IoT applications. In most cases, a new IoT application will also require a tailored piece of hardware (typically a “sensor”) to be deployed at remote locations. Good news is that the design of a smart IoT device has never been easier because many essential hardware building blocks and other ingredients (software, cloud services) are offered as standard products, i.e. there is no need to develop everything from scratch.

My name is Kersten Heins. After my graduation, I spent 30+ years in the industrial computing, smartcard and semiconductor industry where I started as a design engineer (of embedded systems) and moved to customer-focused application and marketing jobs. I always loved technical writing and since Jan 2020, I am now acting 100% as a passionate IoT marketing content creator, focusing on secure endpoint device design. My books and articles are intended to provide some meaningful and independent information for technical-minded IoT fellows, esp. for those who are developing an IoT ecosystem and/or planning to design a new IoT device.

This is a list of my recent publications (in chronological order), last update on Feb 10, 2023:
