Electronics Worksheet: What Is IoT

Electronics lesson 27: What is IoT? · Set 318 · 40 questions

Remember (Sense, send, store, show): IoT device = an everyday thing that shares data over the internet (usually Wi-Fi and an app). Data flow: sensor → board → Wi-Fi → cloud → app (and commands back to an actuator). Readings sent = total time ÷ time between readings, in the same units.
