Week 22 · IoT integration

Internet of Things: from sensor to web dashboard

This is the week everything joins up. Your Arduino measures light and distance, your Python logger carries the readings to your API, the API stores them in a database, and your JavaScript dashboard shows them live. That chain — device to data to screen — is the Internet of Things (IoT), used in smart farms, cold-chain vaccine fridges, water tanks and factories.

Describe the layers of an IoT system (device, connection, server, app)
Send sensor readings from an Arduino over USB serial as CSV lines
Run a Python logger that parses the lines and posts them to the API
Watch live readings appear on the dashboard, and handle bad lines and lost connections
Present the complete sensor-to-web system (Project 5)
