Electronics Worksheet: What Is IoT

Electronics lesson 27: What is IoT? · Set 623 · 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.

2. 2.🔍 Which is the odd one out? (a) a paper calendar (b) a plain wall switch (c) a Wi-Fi weather station (d) a pencil sharpener
3. 3.🌐 In an IoT system, which part shows data to you? (a) sensor (b) microcontroller (c) actuator (d) phone app
