- Touchscreen Interface: The user control panel for temperature, fan speed, etc.
- Sensors: Temperature and humidity sensors that provide feedback to the system.
- Blower Motor & Actuators: Physical components that adjust airflow and vent settings.
- Battery & Power Supply: The power source for all electronic modules.
