February 17, 2026

esp32 esp-idf iot telemetry firmware

This implementation demonstrates a device-to-browser telemetry workflow on ESP32 using MLX90393 sensor data.

What is implemented

  • ESP-IDF v5.5.2 firmware with MLX90393 connected over I2C.
  • Local SoftAP dashboard for quick setup and testing.
  • Real-time telemetry stream over WebSocket with profile controls.

Why this matters

For embedded teams, this pattern is useful when validating sensor behavior, data pipelines, and diagnostics UX before integrating into larger product firmware.
