From 2015 to 2020, I designed and developed web applications for a clinical-grade biometric sensor. In 2020, my company introduced an open-source version of this sensor.
Because our biometric sensor had no user interface, it was difficult for third-party developers to configure it, debug it, or visualize data. We needed a great out-of-the-box developer experience that included a rich UI and “just worked.”
The console allowed developers to connect to a sensor right away, configure it, view high-fidelity data streams, and download sensor data to the desktop.

In just a few lines of code, a developer could connect to a sensor and issue a command. Here, after connecting to a sensor, the sensor says “Hello, World!” by blinking its LED lights:
