> The thing runs on usb 5v so the power consumption is negligible.
There’s a huge leap from that to the power consumption being low enough to be integrated into a smartphone, as demanded by OP.

However, this assumes the sensor would fit in a smartphone, which is not a given. And these things need air flow. And they also wouldn't work while the phone is in a bag or a pocket.
Not sure about that, at least NDIR sensors have to be at certain elevated temperature to work and they do some preheating when you turn them on from standby.
So it's not possible to just measure less often as then energy would have to be spent on heating the sensor.
