Hi, I'm looking to build a system to sense 'steps' of a hall-effect flowmeter.
My first throught is to use a voltage divider and rectifier circuit to get down to the 0-1.8v I need. The problem I have is that every install may potentially have a different input voltage. I'm wondering if there's a simpler way to do this. I really only need to clip the voltage between 0-1.8v, it doesn't matter if it spends 90% of it's time clipped and throws away the negative half of the signal completely as I'm only interested in a count. The current draw will be in the millivolt-range used by the adc input, so it shouldn't need anything too heavy. My first thought is a simple voltage regulator set to 1.8v, but I don't know enough about them to know whether it's a viable option or which to choose.
