Build your own ESP32 plane tracker with off-the-shelf parts
Aviation enthusiasts and hardware tinkerers can now build their own real-time aircraft tracker using nothing more than an ESP32 board and a few low-cost components. The project repurposes existing hardware to deliver live flight data without requiring advanced skills or expensive tools.
From weather station to flight radar
Originally designed as a general-purpose IoT device, the ESP32-based tracker was adapted to receive and decode ADS-B signals—the same broadcasts planes use to share their position, altitude, and speed. A small antenna and a software-defined radio module pick up signals from nearby aircraft, while the ESP32 processes the data and displays it on a local dashboard. Builders can watch flights in real time, log historical patterns, or even feed the information to online flight-tracking networks.
Simple parts, big sky view
The creator behind the project emphasizes that most parts are off-the-shelf and budget-friendly: an ESP32 development board, an RTL-SDR dongle, a simple antenna, and a few jumper wires. Software is open-source, meaning anyone can inspect, modify, or extend the code to suit their needs. The setup is compact enough to sit on a desk or mount outdoors, making it ideal for both indoor monitoring and backyard installations.
A growing wave of open-flight tools
With aviation-focused DIY projects gaining momentum—from ceiling-mounted Raspberry Pi trackers to compact desk units—this ESP32 tracker joins a small but growing ecosystem of open tools for flight enthusiasts. Whether for pure curiosity, educational use, or simply keeping tabs on overhead traffic, the project shows how accessible technology can turn everyday hardware into a live sky-monitoring station.
