Sensor Fleet

IoT Data Pipeline Series

Sensor Fleet: IoT Temperature Monitoring

A hands-on series that turns a practical problem into a full data system. We build Arduino sensors, stream data through MQTT, store and query it in MySQL, and add monitoring, security, and streaming upgrades.

Why this series

Build a system you can measure, trust, and extend

This series turns a real-world energy problem into a full data pipeline. It’s equal parts hardware, software, and insight generation — a blueprint for collecting your own dataset and making it useful.

Hardware

Ship sensors fast

Build and deploy temperature sensors on a lean budget.

Pipeline

Stream + store reliably

Move data from MQTT to a database you can analyze.

Insights

Turn readings into decisions

Layer in weather data, dashboards, and monitoring.
