Real-time temperature controller designed for industrial/laboratory applications. The system leverages the dual-core architecture of the ESP32 to separate the PID regulation logic from the communication stack.

🛠️ Technical Implementation

The project focuses on high-precision thermal regulation with the following stack:

  • FreeRTOS: Multitasking implementation for deterministic PID timing.
  • PID Algorithm: Custom-tuned feedback loop for stabilization.
  • Web Interface: Live monitoring via ESPAsyncWebServer with WebSocket support for real-time graphs.
