Hi, Ive seen a few threads here about using a flow sensor and from what Ive gathered for my use case it is going to be best to use a 2 wire flow sensor. I say this as I am using the OpenSprinkler DC version(which does not have a 5V pin as far as I can tell), and I am powering my device via POE with a splitter.
In any case I was looking for some suggestions or guidance on what 2 wire flow sensor others have used and would suggest
