Hi, I'm working on a raspberry pi water flow meter using this sensor. It uses hall effect sensor to send pulses indicating how much water is flowing.
I plan to test my pi software (I'm planning on using this library) using an XR2006 based signal generator like this one (I have the kit, but haven't assembled it yet). That should approximate the signals coming from the water sensor, right?
However I notice that the square wave amplitude is not adjustable, and is around 8v. Is there something I can do to reduce it to 3.3v so I can use it with the pi? What about running it through a series of diodes to drop the voltage? Or, I have a bunch of Zener diodes, if I find a 3.3v one, would that work? I do have an occilcope so could measure the output before hooking it up to the pi.
Thanks.
