Getting Started Open Echo Interface Software

The Open Echo Web Interface is a cross-platform Python application that interacts with the Arduino + TUSS4470 Shield. It displays ultrasonic echo data in real-time in the browser using a waterfall chart visualization.

Key Features

• Connects to Open Echo hardware over serial
• Displays real-time and historical data in a waterfall chart
• Shows detected depth
• Shows depth at cursor on hover - useful for precise depths of non-ground echoes (fish!)

Note
This interface is primarily intended for development and testing. It’s proven stable, but not yet a polished end-user application.
