Intelligent Solutions for Smart Buildings

Create the Smart Buildings of tomorrow with Infineon sensor and power solutions

Smart Buildings are on the rise. Thanks to advancements in sensor and communication technology, buildings are becoming more and more intelligent. With a higher level of smartification, buildings increase their energy efficiency thus lowering their carbon-dioxide footprint and energy consumption. At the same time, smart buildings offer their occupants a higher level of comfort thanks to adaptive and intuitive building operations.

Smart devices are a key element for the intelligent buildings of tomorrow. Thanks to sensor technology, building equipment such as HVAC devices become smart enough to be able to monitor their condition. Infineon’s range of XENSIV™ sensors including pressure sensors, MEMS microphones, current sensors, 3D magnetic sensors along others together with its XMC™ product portfolio enables condition monitoring and predictive maintenance features.

Additionally, these sensors can be used for room automation. Together with Infineon’s XENSIV™ radar chip, the presence and number of people can be detected to adjust operations of lighting, HVAC devices and other domains in a building automatically.  

A reliable and power-efficient information and telecommunications technology (ICT) infrastructure is crucial to enable these smart features. With Power over Ethernet (PoE), power and connectivity can be provided to smart devices inside the building via one single twisted-pair Ethernet cable.

Thanks to the latest IEEE 802.3bt PoE standard, up to 100 W per port is available from PoE Power Sourcing Equipment (PSE) that opens the door for many new PoE applications on the Powered Device (PD) side. At the same time, it creates new challenges for the power design of the PoE equipment. Now, even under wide-load conditions highest power efficiency is requested. Thanks to Infineon’s portfolio of efficient high and low power semiconductors like the CoolMOS™ or OptiMOS™ family, these challenges can be addressed.
