ESP32S3 firmware for NexBell door sensor and audio streaming
The project provides a complete ESP32S3 firmware that ties together an ultrasonic distance sensor, a magnetic door sensor, and an INMP441 microphone, publishing presence, door state, and audio chunks over MQTT. Users configure Wi‑Fi and broker settings, build with PlatformIO, and flash the device to get instant telemetry and remote unlock capability. It targets makers and IoT developers who need a turnkey door‑monitor and audio‑capture solution. Unlike generic examples, it combines multiple sensors and audio streaming in one cohesive, production‑ready package.
