The IAQ platform is a product solution that is ready for the market. Different types of business models can be introduced to scale the potential of application and penetration in residential and commercial areas. In family houses and flats, the sensor can control the systems based on user’s behaviour and provide a signal to open the windows to let the fresh air in. In commercial areas, the sensor can be used to automatically maintain a proper indoor environment by controlling air handling units as a component of a complex BMS system. In both cases, it provides monitoring data for long-term evaluation of indoor environment conditions. This can further help improve the environment which is so important for us.
