- What is the Internet of Things (IoT)?A plain introduction to the Internet of Things: what counts as an IoT device, how the idea grew, why the number of devices matters, and everyday examples you already use. 7 min · Beginner
- The building blocks of an IoT systemThe five parts every IoT solution is built from: device, connectivity, platform, application and user, with what each part does and where security fits in. 7 min · Beginner
- IoT use cases: homes, healthcare, farming, cities, logistics and retailPractical IoT use cases across six sectors, what problem each solves, what data it collects, and the security and privacy issues that come with it. 8 min · Beginner
- Microcontrollers vs single-board computers: Arduino, ESP32 and Raspberry PiHow microcontrollers and single-board computers differ in power, memory, operating system and security, and how to choose between an Arduino, an ESP32 and a Raspberry Pi for a project. 8 min · Beginner
- Sensors and actuators: how IoT devices sense and actWhat sensors and actuators are, the common types, the difference between analogue and digital signals, and how a raw reading becomes trustworthy data. 8 min · Beginner
- The IoT data lifecycle: collect, transmit, store, analyse, act, deleteFollow IoT data through its six lifecycle stages, from the moment a sensor takes a reading to secure deletion, with the security and privacy controls needed at each step. 8 min · Beginner
- Powering IoT devices: batteries, sleep modes and energy harvestingHow IoT devices are powered, how to estimate battery life, the low-power design techniques that make years on a battery possible, and how power limits affect security choices. 8 min · Intermediate
- Device, edge, fog and cloud: where IoT data is processedExplains the four places IoT data can be processed, from the device itself to the cloud, and how to decide where each job should run based on latency, bandwidth, privacy and cost. 8 min · Intermediate
- IoT challenges: security, privacy, interoperability, scale and lifetimeThe main challenges that make IoT hard to build and run safely, including weak security, privacy concerns, incompatible standards, sheer scale and devices that outlive their support. 8 min · Beginner
