Hi There is an ever increasing pool of good sensors to put into something like this. (More so for temperature and pressure. Humidity still is a bit of an issue.) There’s not a lot to interface between the sensor and a USB “chip”. It’s surprising that there aren’t more cheap / high accuracy choices out there.
