I'm not sure if this would be better off tackled through a micro-controller or a series of gates and analog building blocks but I'm looking for some direction.
I want to take a series of sensor ohm reading measurements (referenced to ground) and if they read zero or close to it I want to give an on signal output for that particular sensor.
After this I'd like it also to go through an OR Gate (or NOR) and be output to a main output.
Would I be better off using a micro-controller?
If not and I go old school logic what would I use to pickup the sensor's ohm reading outputs.
I guess to complicate things a little more, sometimes the ohm reading will be a range and a certain range will output a ONE or ON condition. I've used microcontrolers before and it seems like the analog ins work great for programming a range. But if I go the logic chip route, what part would I use to sense the range of ohm readings that are acceptable?
