I have a 3 wire flow sensor.
5v , common and signal wire.
Signal is a blockwave.
I cannot get it to work. I use opensprinkler software ( because i did not receive any software with the pi version of the tiao board , and downloaded the tiao software at least 5 times but file is always corrupt)
Anyhow. Does anyone else use a flowsensor and does anyone have any good advice how to get it working ?
