Commenting on my own project...We've been using this for a couple of weeks now and I have determined that the system eat 9V batteries like Cookie Monster. If you create your own version, I suggest using the 8x AA battery pack instead.

I actually wondered if the PIR sensor wouldn't become saturated and not see the person just because of that reason (no discernible temperature differential). I'm not sure how well they sense through glass shower doors either.Well, it's not perfect anyway, but seems to be doing the trick so far :-)

Thank you!

That's an interesting approach :-)In addition to the shower, we have one with a make-up routine that takes a long time.

In the software, you change both the number of LEDs in the chain (each LED added/removed adds/removes one more TimeInt to the total time). You can also change the TimeInt value to something lower. For example, to limit to close to 20min using 3 LEDs, you could set TimeInt = 7 and have a total of 21min.

I think that the addition of a motion sensor makes a lot of sense for a half bath, especially for kids that spend a lot time on makeup and "fixing" themselves :-)In the shower scenario, I not sure if a motion detector would detect a person in the shower or not.

Can you post an instruction for this? It is very similar to what I'd like to do.Thank you!
