Though the Covid pandemic is receding, the concern for monitoring air quality is rising, which in turn creating demand for sensors to detect carbon dioxide in the air. You can find lot of carbon dioxide sensors in the market but they all fit more for the industrial control applications. When it comes to integrating carbon dioxide sensors in IoT powered consumer electronics, wearables, and smart phones, you need a compact, very small size and less costing sensors. We still don't have the one that is small enough to be integrated into smart phones and wearables, but it is progressing in that direction. Infineon technologies has made available a compact sensor sensing carbon dioxide using a technology called photoacoustic spectroscopy. This surface-mount mems-based sensor measures 14 x 13.8 x 7.46 mm in size. This sensor is quite big compared to many other sensors getting into wearables, but it is still 75% smaller than other CO2 sensors in the market. This is very ideal for smart home automation electronics. It can also be fitted into air-conditioners, room ventilators or any such non-mobile electronics-integrated air service providing home appliances. Infineon claims this sensor provides superior accuracy and provide direct readout of the real CO2 level.
