CO2 sensors for a more efficient and healthier environment

CO2 sensors for a more efficient and healthier environment

First question asked First like given Welcome!

As a child, I had always struggled with allergies. This has made me particularly sensitive to the quality of air around me. Unfortunately, we cannot see the air quality, and we cannot see what is causing us issues with our well-being. But wouldn’t that be a good option to have? I have always thought about the idea of how we could detect the air quality in order to be able to have the information we need and want.

Even as an adult, I have remained acutely aware of my surroundings and the impact they on my health, knowing we spend 90% or more of our time indoors; at home, in the office, in public transport or at the gym. You cannot see the air quality, but you will certainly feel it – unfortunately often too late. One key air quality factor that can also have a major impact on our well-being is carbon dioxide, which is actually produced by ourselves while breathing. For example, too high a level of CO2 is a warning that people could become drowsy, unconcentrated or if exposed for too long, it can result in headaches.

Related to this matter, on today’s blog, I will talk about Infineon’s XENSIV™ PAS CO2 sensor which is used in various settings to continuously monitor and manage air quality and in addition supports energy efficient ventilation saving up to 30% of energy cost in buildings.

Fortunately, today CO2 sensors are small and accurate so they are ideal for deployment in IoT devices to provide an easy way to continuously monitor air quality in homes, offices, shops, factories and other environments. Firstly, for the well-being of residents, staff or visitors and secondly, for reducing HVAC (Heating, Ventilation, Air Conditioning) costs by providing real time data to continuously optimize and manage demand-controlled ventilation.

Infineon’s XENSIV™ PAS CO2 uses the PAS (photoacoustic spectroscopy) principle where the light from a light source excites the CO2 molecules in the sensing chamber, which creates a pressure effect that is converted into an electrical signal. It is fast and accurate as based on real CO2 concentration. The nice thing is, that the size of the PAS sensor is four times smaller than NDIR solutions in the market, as it fits in a very small form factor of a SMD (Surface Mounted Device) package. This facilitates the widespread deployment of these sensors in smart homes and facility management settings.

Infineon’s PAS CO2 meets the mandatory requirements of the California Energy code for smart and sustainable buildings. In addition, the XENSIV™ PAS CO2 sensor supports a cost-effective implementation of WELL and LEED Green Building.

CO2 sensors provide various value-added and ROI (Return on Investment) generating functionalities in the areas of smart homes, smart buildings, facilities management, as well as other industrial settings so their use will become increasingly widespread. With its XENSIV™ PAS CO2 sensor, Infineon is delivering world class CO2 functionalities at affordable prices. Infineon’s CO2 sensing devices can set your HVAC system or IoT device apart from the rest and help you excel in a highly competitive landscape.

As someone who has always been passionate about understanding the air quality, I believe that the use of CO2 sensors is an important step in the right direction. By providing vital information about air quality and helping to reduce energy consumption, these sensors have the potential to make a significant impact on our world. They literally drive carbonization.

I am excited to see how this technology will continue to evolve and improve, and I look forward to a future where CO2 sensors are a ubiquitous part of our everyday lives, helping to ensure that we breathe clean, healthy air and live in a more sustainable world.
