Is it even possible to monitor fir helium levels? It’s an inert gas, so I’m not sure if it’s easily detectable directly.

Yes we use helium sensors for analyzing diving gas mixtures. They infer helium concentration based on the thermal conductivity of the gas; there's no chemical reaction.

Yes, with iPhones!
