The Concept

Connecting the physical world to robust cloud applications requires precise firmware and reliable hardware. This project focuses on building a centralized smart controller capable of aggregating signals from diverse sensor types—temperature, humidity, motion, and light—and transmitting them efficiently via MQTT protocols.

Future Milestones

  • Hardware Design: Designing a custom PCB integrating the ESP32 module with cleanly routed traces for auxiliary sensor connections.
  • Firmware Development: Writing C++ utilizing FreeRTOS concepts for multi-threading to ensure sensor reads don't block the network transmission loops.
  • Cloud Platform Setup: Connecting to an AWS IoT Core or local Mosquitto broker to store and dispatch actionable alerts.
