Key Concepts & Vocabulary
TermDefinitionExample
Internet of Things (IoT)A vast network of physical objects—'things'—embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the internet.A smart home system where your lights, thermostat, and security cameras are all connected and can be controlled from your phone.
IoT DeviceA physical object, often equipped with sensors, software, and network connectivity, that can collect and exchange data over the internet.A smart doorbell with a camera that sends video to your phone when someone rings it.
SensorA device that detects and responds to some type of input from the physical environment, converting physical phenomena (like temperature, light, motion) into electrical signals.A...

Core Syntax & Patterns
The Sensor-Process-Actuator Loop
Many IoT systems operate by sensing data from the environment, processing that data (either locally or in the cloud), and then actuating a physical response.
This rule describes the fundamental operational cycle of many IoT systems. An IoT device gathers information (Sense), makes a decision based on that information (Process), and then performs an action (Actuate).
Connectivity is Essential
For an object to be considered part of the 'Internet of Things,' it must have the capability to connect to a network (like the internet) and exchange data.
This highlights the defining characteristic of IoT. Without the ability to communicate over a network, a device might be 'smart' but it is not an IoT device.
