The Munich-based company announced on Tuesday at the CES technology fair in Las Vegas that it would be accommodated in various devices such as air conditioning, room monitoring or networked speakers.
Infineon sees a market for the technology, on the one hand, through the increasing demands on energy efficiency – in order to only have to ventilate when it is necessary and to let out little cold in summer and little heat in winter. In California, for example, even the ventilation systems in private homes have to run on CO2-Sensors are equipped.
Infineon manager Philipp von Schierstädt also specifically referred to the benefits in the pandemic due to the connection between CO2 and aerosols in the air. “With increasing CO2Level increases the risk of being infected. “Infineon installed the sensors in its own meeting rooms.” With this, we want to ensure that there is always a low CO in all meeting rooms2-Value and therefore a low aerosol content to protect employees. “
The sensor, called Xensiv PAS, works with photoacoustic spectroscopy. Light with a certain wavelength is passed into a chamber with ambient air. The CO2-Molecules absorb the light – and the intensity of their reaction is measured with a microphone. This becomes the CO2-Calculated salary. “You really have real values,” emphasized von Schierstädt.
Infineon can also combine sensors, for example radar and CO2-Measurement to connect. So you wouldn’t just get the CO2– Determine the content, but also recognize where people are and need to be ventilated. “It is best for the customer to get a complete solution from a single source.” With dimensions of 14 by 13.8 by 7.5 millimeters, the sensor is also around four times smaller than current high-end technology.
Infineon is also working on the measurement of other gases with photoacoustic technology, also outdoors. “We want to become the most important provider in the medium term,” announced von Schierstädt. The company is also thinking about the protection of innovations: “We are covered quite well with 200 patents.” (dpa / rs)
