Smart BLDC Ventilation Fan

Ventilation in buildings is crucial, as a lack of clean air supply can harm health and quality of life. In the UK, ventilation requirements are part of building regulations. According to a report from market researcher BRE, poor housing costs the National Health Service in the UK £2.5 billion in treatment costs. Poor indoor air quality has been linked to allergies, asthma, and other chronic diseases. High levels of CO₂ can cause drowsiness, lack of concentration, and headaches.

This BLDC fan controller system is designed for smart building automation applications, offering configurable limits. The energy-efficient BLDC control reduces operating costs while enhancing fan performance.

System Benefits:

• Energy-efficient BLDC control for fans reduces operating costs and enhances performance.
  • Fan activates only when volatile organic compounds (VOCs), moisture, or CO₂ are detected.
• High-performance motor control MCU + FPU includes all functions needed for efficient BLDC motor control, simplifying development.
• Versatile design with configurable alarm/interrupt output features static and adaptive levels.
