Key Concepts

Three Ingredients Test: Simple filter for deciding whether a product qualifies as IoT: physical thing, embedded computation, and internet reach.

Gateway Distinction: Local wireless is not the same as internet connectivity; many products remain merely connected unless a gateway gives them remote reach.
Five-Layer Architecture: Teaching model that separates physical devices, edge logic, connectivity, cloud functions, and applications.
Characteristic Prioritization: The eleven qualities of strong IoT systems are design goals that must be weighted differently by domain.

Major section

Definition

The Internet of Things (IoT) is the concept of connecting everyday physical objects to the internet.

These objects can range from household appliances to industrial machinery, enabling them to collect, exchange, and act upon data.
Simple Definition:: At its core, the Internet of Things refers to the interconnection of physical devices with the internet.

IoT ecosystem framework adapted from the Edinburgh Design Course.

Major section

Examples of IoT Devices

Microwave:: A connected microwave can be programmed via a smartphone.

Washing machine:: A smart washing machine monitors energy use and sends notifications when cycles are complete.
Coffee machine:: A coffee machine can be scheduled to brew automatically at specific times.
Truck:: A connected truck uses sensors to track location, fuel efficiency, and maintenance needs.

Everyday objects that can become IoT devices.

Major section

Complete IoT Architecture Layers

Example: Wi-Fi sends a reading to the cloud.

Application layer:: Mobile apps, dashboards, automation rules, alerts, and reports deliver user value.
Example: an app shows energy savings.

Five-layer IoT architecture stack from physical devices to user-facing applications.

Major section

Minimum Requirements of IoT

These components ensure the object can perform smart functions and communicate effectively within an IoT ecosystem.

These objects are made "smart" by adding computational and connectivity features.
Computation:: Objects must be enhanced with computational capabilities to process data, execute tasks, and enable intelligent behavior.
Internet Connectivity:: Connectivity is the defining feature of IoT devices.

Major section

Device Classification Decision Tree

Its diagram makes Classify Before You Call It IoT and: YES means continue downward explicit within decision tree for classifying software, embedded, connected, and iot products.

That labelled check bounds decision tree for classifying software, embedded, connected, and iot products.

Major section

Warehouse Tech Selection Check

Scenario:: Your logistics company wants to monitor temperature and humidity in 50 warehouses (200,000+ sq ft each) across the country to protect sensitive pharmaceutical inventory worth $2.5B annually.

FDA compliance requires documented temperature control.
Approach A (Wi-Fi): $50 sensors, $10/month/warehouse, 30-second updates, requires Wi-Fi infrastructure Approach B (LoRaWAN): $80 sensors + $200 gateway, $5/month/warehouse, 10-minute updates, 10-year battery.
Key Insight:: IoT technology selection depends on application requirements, not "newest" or "fastest" technology.

Q1A smart irrigation valve has a soil moisture sensor, a microcontroller to open/close the valve, and LoRaWAN connectivity to a cloud platform that schedules watering based on weather forecasts. Which of the Three Minimum Requirements does the LoRaWAN radio fulfill?

AThe Thing requirement -- LoRaWAN is the physical radio hardware

BThe Computation requirement -- the radio processes data before transmitting

CThe Internet Connectivity requirement -- LoRaWAN provides the link to the cloud platform

DNone -- LoRaWAN is not a true internet protocol

Show answer

Answer: C LoRaWAN provides the Internet Connectivity ingredient by connecting the sensor node to a gateway that bridges to the internet.
