    This project develops an ESP32-based differential pressure measurement module using the Sensirion SDP810-500Pa sensor for ventilation diagnostics (Ventilation OBD system). The device measures airflow pressure differences across filters, ducts, and fans to evaluate system performance and detect blockages or imbalances.
