Learning objectives

You will be able to:

  • Trace how sensing, edge compute, BLE, and cloud services enable an IoT product.
  • Test a product benefit against battery, privacy, and operating-cost limits.
  • trace how sensing, edge compute, BLE, and cloud services enable an IoT product
  • test a product benefit against battery, privacy, and operating-cost limits

IoT Products (2010s-Present)

Machine learning: Learns patterns and improves over time.

  • Example: A smart washing machine that automatically selects optimal washing cycles based on water usage, energy efficiency, and load type.
  • It detects fabric types via sensors, learns your usage patterns (you always wash jeans on Wednesdays), adjusts water temperature based on energy prices from the smart grid, and orders detergent automatically when running low.
  • Integrates with smart home ecosystem (starts cycle when solar panels generate excess power).

Common Pitfalls and Misconceptions

A light bulb controlled from a phone can meet the baseline IoT test, but it should not be sold as adaptive.

  • A more mature lighting system may learn a routine, use ambient-light sensors, and coordinate with other devices.
  • Confusing Connectivity with Intelligence:: Connectivity can establish an IoT data path, but it does not prove intelligence.
  • Ignoring the Embedded Foundation:: IoT devices do not replace embedded systems -- they build on top of them.

Why it matters

The distinction matters because products lose trust when basic connectivity is sold as autonomous optimisation.

Common Pitfalls and Misconceptions (continued)

A thermostat with an app is connected IoT; a thermostat that learns your schedule and adjusts from occupancy, weather, and energy prices is adaptive IoT.

  • Every IoT device still contains an embedded core that must balance the cost-power-performance triangle.
  • Assuming Linear Evolution:: Not every product should become connected or adaptive.
  • A simple kitchen timer can remain embedded; it does not need ML or cloud analytics.

Common Pitfalls and Misconceptions (continued)

The distinction matters because products lose trust when basic connectivity is sold as autonomous optimisation.

  • Forcing connectivity or intelligence into products where users do not need it adds cost, complexity, and attack surface without proportional value.
  • Overlooking the Ecosystem Opportunity:: Ecosystem integration is not required for baseline IoT, but it can extend value.
  • A thermostat may gain useful capabilities by coordinating with a home platform, blinds, and occupancy sensors.

Defining Principle

"An embedded system is a computerized system that is purpose-built for its application.": Elicia White, Making Embedded Systems (O'Reilly).

  • Unlike desktop software where you can always throw more RAM or CPU at a problem, embedded systems force engineers to make hard trade-offs.

Defining Principle (continued)

Purpose-Built Functionality:: Embedded systems are designed to perform a single, specialized task, making them highly efficient in operation.

  • Low Power Consumption:: Due to their focused functionality, embedded systems operate with minimal power requirements, allowing them to fit in small spaces and extend device longevity.
  • Cost-Effective:: Embedded systems are typically inexpensive, making them an economical solution for controlling devices in various applications.

Phoebe's Field Notes: What The "Coin Cell For A Year" Claim Actually Budgets

The mathematical gist.: A 225 mAh CR2032 at 3.0 V stores 0.675 Wh by nameplate.

  • One year of 1% self-discharge leaves 222.75 mAh, so charge, energy, pulse sag, and retention must be checked together.

Numbers to remember

0.240 V20 ohms of fresh-cell resistance drops 0.240 V and leaves 2.76 V
2.76 Vleaves 2.76 V
1.20 Vleaves only 1.20 V.
