I have successfully been able to interface the raspberry pi 3 (running the latest raspbian distro [Jessie]) with a liquid flow sensor I bought from Adafruit Industries (here is the link to the flow sensor: https://www.adafruit.com/products/828). My problem is, is that I do not know how to receive output from the sensor in a workable form - right now the indicator widget I am using alternates between 0 and 1. I need something more than just ones and zeroes - feel like I should be getting back different values since the sensor operates using the Hall effect.
Anyone know what I can do to make this system I am working on more effective (meaning simply receiving output data I can use to model trends with from the sensor to the RPi3)?
Thank you and I look forward to your responses.
