I Started Looking at IoT as a Data Pipeline

When I first think about IoT, I usually think about the device.

A sensor measures something.

Done, right?

Not really.

The interesting part starts after the sensor collects the data.

You might have something like:

Sensor
↓
Device
↓
Network
↓
MQTT / HTTP
↓
Backend
↓
Database
↓
Analytics
↓
Dashboard

And every arrow in that diagram can become a problem.

What happens if the device goes offline?

What if the same message arrives twice?

What if the sensor sends a completely unrealistic value?

What if 10,000 devices start sending data at the same time?

That's why I think of IoT less as "connecting devices" and more as building a reliable data pipeline between the physical world and software.

The sensor is just the beginning.
