What's the best way to detect when I'm taking a shower? (lemmy.world)

I would like to turn on mood lighting automatically when I'm taking a shower, what's the best way to detect that?

  • I've considered humidity sensors, but that will take a while to kick in and not immediately when the shower starts.
  • I've also considered a water leak sensor but those are not meant to be trigger every day for a long time like 10-15 minutes. That would kill the battery, right?
  • Smart valves can kind of work, but it feels like overkill because I don't care about the valve functionality.

I would prefer the solution to be battery powered (don't want to be messing with too many cables around a shower), but I can't seem to find one.

I bet you can rig up something microphone-based, there's tons of software nowadays for analyzing audio, and you don't need to run the analyzing software on the device with the microphone anyway. Though the analyzing would likely take a little bit longer that you'd want it to.

Microphone is certainly an interesting choice I hadn't thought of before at all. It's something I can test easily, I'll have to see how well it plays with music too. I'll give it a shot
