Open-source software and hardware are key drivers in the democratization of technology, making powerful tools accessible to everyone. Grafana, an open-source observability platform, helps users visualize and understand their data where it lives—whether from databases, IoT sensors, cloud services, or other sources. Paired with the ESP32, a versatile microcontroller, developers, educators, and enthusiasts can build innovative and practical projects. What better way to explore this than with a fun, hands-on application: monitoring a drone’s telemetry in real time?

In this talk, we will demonstrate how to use Grafana with an ESP32-based drone system to collect and visualize IoT telemetry. We will walk through setting up the development environment, flashing firmware, and configuring Grafana Cloud for real-time data analysis. Attendees will gain practical insights into integrating IoT devices with visualization tools for telemetry data analysis.

The presentation can be delivered in both English and Spanish.
