I'm going to try and sound as intelligent as I can about this. I was an EE minor in college, so I remember some stuff ;-)
I'm getting lawn sprinkler leaks, and I'd like to know exactly when my water in the irrigation system is flowing. I don't care how much is flowing, just an ON/OFF signal.
There are several flow sensors on the market, this seems to be the best one not completely locked into a proprietary controller:
- **broken link removed**
- **broken link removed**
It says:
The flow sensors generate a frequency which is proportional to flow
rate.... Power to operate the sensor is provided by the flow monitor... As
the liquid flow turns the impeller, a low impedance signal is transmitted
with a frequency proportional to the flow rate.
Like I said, I really just want ON/OFF, YES/NO.. so I can control a light or chirping buzzer with a relay or something.
Is there a fairly easy way to:
- send it power? 5V? 12V
- Determine that ANY "a low impedance signal" is being sent?
I'm handy with a soldering iron and a volt meter.. but not with this type of detail. I clearly don't want the $200-$500 full solution,
a $100 sensor and some misc bits is what I want.
Thoughts?
Any help is much appreciated, and in return, I'll give back and put up a nice final project description and pictures to help others out.
