It's not really "finally". They introduced a similar sensor, the PASCO2V01, a couple years ago. That one has been available on a breakout board with the necessary support hardware from SparkFun for over a year [1]. Comparing the datasheets for the PASCO2V01 and the new PASCO2V15 the old one actually seems a little better as far as CO2 measuring performance goes. They are the same on most things, but the old one has slightly better accuracy. The new one is ±(50 ppm + 5%) between 400 ppm and 3000 ppm. The old one is ±(30 ppm + 3%) between 400 ppm and 5000 ppm. The big difference is this: > Infineon has recently introduced the PASCO2V15, a new 5 V sensor to improve air quality monitoring in building environments. Both of them require a dual voltage power supply. They both want 3.3 V for their digital components and a higher voltage for their IR emitter. For the older one that higher voltage is 12 V. For the newer it is 5 V. [1] https://www.sparkfun.com/products/22956 https://www.sparkfun.com/products/22956
