I am trying to read from the SGX MICS-6814 gas sensor. The documentation has 2 small sections on how to read the output:
To start with they show the resister order differently. But mostly I don't quite understand what they are saying about switching resisters. I am using a 16bit ADC and they don't really give any indication how to work out what load resistor/s to use. Can anyone at least explain what the theory of what they are trying convey?
