Internet of Things Applications

This week, the Raspberry Pi Foundation announced it has sold more than 10 million Raspberry Pi boards and celebrated the milestone by releasing a new Raspberry Pi Starter Kit. While many of these Linux-driven hacker boards were used for the foundation’s original purpose -- creating a low-cost computer for computer education -- a large percentage have been sold to hobbyists and commercial developers working on Internet of Things (IoT) projects ranging from home automation to industrial sensor networks.



Linux-driven open source and commercial single board computers and modules sit at the heart of the IoT phenomenon. They are usually found in the form of gateways or hubs that aggregate sensor data from typically wirelessly enabled, sensor-equipped endpoints. Sometimes these endpoints run Linux as well, but these are more often simpler, lower-power MCU-driven devices such as Arduino-based devices. Linux and Windows run the show in the newly IoT-savvy cloud platforms that are emerging to monitor systems and analyze data fed from the gateways in so-called fog ecosystems.

Over the next few weeks, I’ll be analyzing the IoT universe, with a special focus on Linux and other open source technologies used in home and industrial automation. I’ll look at major open source products and projects, IoT-oriented hacker boards, security and privacy issues, and future trends.
