Electronics Worksheet: What Is IoT

Electronics lesson 27: What is IoT? · Set 267 · 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.🌐 Each reading a sensor sends is 50 bytes. How many bytes do 50 readings take?
3. 3.Which of these is not an IoT device? (a) a pencil sharpener (b) a Wi-Fi weather station (c) a fitness band with app (d) a smart energy meter
4. 4.🔢 To get a sensor reading onto a phone, which is the LAST step? (a) the app shows it (b) the board reads it (c) it is sent by Wi-Fi (d) the cloud stores it
