Aiber Water flow sensor

Thanks for making me check it, which was a fairly tricky exercise
Sticky tape over opening to create air seal of sorts
But I can confirm, it spins, not fast, but definitely spinning
Also discovered that even a 2 sec video is 5mb

Hello,

You can not measure the pulses when the sensor is open.
It can well be that it spins now, but will not spin when the cover with the magnet is mounted, due to friction.

Good point

Hello,

You could make an electronic anemometer (wind speed) measurement device.
This page shows you several designs with comparison between them:

Use water and a small aquarium pump to create a steady flow of liquid?

Thanks Harald
I've never had a fish tank so small aquarium pump unobtainium here

Thank you for that link to Johan's research--he was quite an interesting fellow.
