Air conditioning systems are joining the ever-expanding list of “things” that are connecting to the Internet of Things. This is reflecting – and also driving – shifts in consumer expectations around aircon systems.
Standard/basic functionality such as stable and smooth start-up plus variable operating speeds and vibration suppression are considered essential must-haves. In addition, cooling systems in private homes must be quiet. Today’s heating ventilation and air conditioning (HVAC) systems should also be equipped with power devices that make them more energy efficient. In keeping with the smart trend among household appliances, home owners additionally expect smart air conditioners to offer various intelligent features that make life more convenient. And as more and more air conditioning units are connecting to the cloud, secure communication and interoperability within the home automation network are growing in importance.

COVID-19 has rapidly increased the need for social distancing solutions in public buildings. The smart entrance counter is one such solution. It counts when a person enters or leaves a building or a room, and simultaneously ensures social distancing. The system uses a 60-GHz radar sensor and integrated software; people are counted accurately and anonymously. A traffic-light system tells people whether access is permitted or not.
The expected demand for this type of solution amounts to 90 million units globally. The system is easy to install and is simply mounted to the wall or ceiling of an entrance/exit area. It can be used in any type of building, including public buildings, retail stores and grocery stores, restaurants, schools, and corporate spaces, such as canteens, offices, etc.
Sensors make homes and buildings smart by enabling them to “see”, “feel” and “hear” their environment – just like our human five senses do.
A smart building or home becomes smart through its connected and intelligent devices that are placed inside of it, for example heating, ventilation and air conditioning, elevators, access control, lighting, energy supply, or water heating systems. These elements itself are not smart. However, when equipped with the right technology, they are able to “see”, “hear” and “understand” their surroundings and perform appropriate actions. Sensors are the neural system of a building that collect in real-time data about a building’s operation, environment and its devices.
Reflecting our holistic approach to IoT design, our vision is to complement our XENSIV™ sensors with state-of-the-art software to create a comprehensive picture of the world around us. Our broad sensor portfolio spans MEMS microphones, plus pressure, radar, environmental, and 3D image sensors (REAL3™). All of which enable designers to create more intelligent, contextually aware devices.
Sensors are the starting point of the Internet of Things. The more precisely they capture data, the more reliable the applications based on them will be. The number of possible use cases is large.

Although everyone has an intuitive sense of when a meeting gets "stuffy", unfortunately we humans don't have anything like sensors for ambient air quality. But Infineon does!
Indoor spaces with increased CO2 concentration levels not only have poor air quality which can for example cause headaches, here we also find raised levels of aerosol concentration – one of the most common transmission paths for COVID-19. Regular ventilation is a good preventive step, but who wants to spend lots of time sitting in a draft of cold air? Wouldn't it be great if we could only air out meeting rooms whenever it's really necessary!

Highly reliable solutions unleashing the benefits of condition-based monitoring vs predictive maintenance with Infineon’s XENSIV™ sensor portfolio
Time and again, malfunctions in heating, ventilation, air-conditioning and refrigeration technology systems interrupt working processes and increase maintenance costs. Predictive maintenance, which is a data-based maintenance strategy for predicting system malfunctions, can be an effective solution to this. To illustrate the benefits of using a sensor-based solution, Infineon has collaborated with Klika Tech and AWS to develop a sensor-based evaluation kit. It enables the straightforward evaluation of condition monitoring and predictive maintenance. Using a range of sensors, paired with microcontrollers, embedded security, and software, it is possible to monitor various parameters of vital components such as compressors, motors, and fans in real time, so that any potential anomalies can be detected immediately. If this is the case, the respective maintenance technicians can be informed in good time – before a malfunction – to address the problem, e.g. by replacing a wearing part or cleaning an air filter.
Infineon’s broad range of XENSIV™ sensors can be deployed to monitor everything from single components of production machinery to an entire smart building ecosystem. Typical use cases include HVAC equipment where XENSIV sensors monitor current, vibration, and airflow in motors, compressors, and fans. These sensors can be combined with FreeRTOS-certified XMC™ microcontrollers and OPTIGA™ security solutions so the data collected can be processed and analyzed to enable advanced IoT features such as predictive maintenance. Using our differentiated memory solutions including SEMPERTM NOR Flash and EXCELONTM F-RAM to reliably and safely store collected data for such analysis, overall system health and safety can be monitored.
Across the globe, leading manufacturers and suppliers of smart home devices are collaborating to develop a global standard for the smart home. The working group "Connected Home over IP" from Zigbee Alliance wants to increase the compatibility and the security of smart home products and simplify their use. This is because aspects such as secure and easy installation and control of smart home solutions are becoming important criteria for consumers when making their purchasing decision.
With the Connected Home over IP standard, the identity of a device can be saved and updated within a hardware-based security system throughout its entire life cycle – from the design phase through to scrapping. This means users can dispense with weak passwords, protect device integrity through secure firmware updates, and encrypt private data according to the state of the art. The Connected Home over IP standard is meant to help manufacturers significantly increase the level of security of smart home devices, whilst also keeping costs and complexity as low as possible – thanks to the easy-to-integrate security hardware.
Power over Ethernet (PoE) means that sensors and other IoT devices in building technology can be installed much more quickly, as the LAN cable doesn't just transfer the data, but simultaneously supplies the devices with power, as well. Although PoE has been around for a number of years, the latest standard IEEE 802.3bt has provided for an increase in the maximum power available, this can be achieved by using a twisted-pair Ethernet cable. This means that is now possible to supply power of up to 100 W per connection. A PoE switch can supply several devices with power at once by simply connecting the devices to the switch using conventional Ethernet cables. This simplifies both the installation process and any subsequent reconfigurations of the building technology systems.
The advantages of PoE are being leveraged by "The Edge", an innovative office building in Amsterdam, which was fitted with 650 PoE switches. These enable users to control the lights and temperature, for example, by means of a smartphone app. Thus, the facility manager has a clear overview of all of the building functions and can maximize the efficiency of the building operations. Over a 20-month period, it was possible to reduce the costs per employee by more than 1,800 euros.
