Hi biswajitjei02.

I’m not sure we have any sensors that would be good at detecting flow in a pipe.

The Piezo Vibration Sensor might work but that’s not anything we’ve tried before. You’d need to connect one to a pipe and see what happens.

As far as rain goes, you would want to keep these dry to prevent any damage to them so you’d need to figure a way to protect them from moisture.
