About IoT Plain Guide

An independent plain-language guide to connected devices: smart homes, cities, farms, factories, health, security and where IoT is heading.

Who this site is for

Curious homeowners, students and professionals who want to understand how connected devices work and what to watch out for.

How the guides are written

  • Answer first. Each guide leads with the direct answer, then explains the why and the how.
  • Practical numbers. Concrete values you can use, with ranges rather than false precision.
  • Connected, not repeated. Short, focused articles link to the in-depth guide for their topic, so you can go as deep as you need.
  • Dated. Every article shows when it was published.
