1. How WIZnet Products Are Used The project uses MCXN236 development board as the main MCU. For IoT connectivity, a WIZnet WizFi360 shield is used, enabling Wi‑Fi-based data upload and remote commands. This setup covers sensor data collection, control of actuators (fan), and network communication — showing WIZnet modules can support a full-stack embedded IoT solution. 2. Technical Implementation & Methods Sensor: BME688 measures VOC and other air‑quality parameters, communicating over I²C to the MCU. Fan Control: EMC2101 drives a DC fan with adjustable speed via I²C under MCU control…
