Hi,
I am going to interface a Figaro Methane Gas sensor TGS2611. Its
characteristic depends on the temperature T and humidity H.
Suppose I can get these information, how do I calculate the relative
sensor resistance R/Ro? The data*** only has a figure about the
temperature and humidity dependency but not mentions any calculation
method such as temperature/humidity coefficients
1)Ask the manufacturer for more acuurate data
2)You fit a straight line, a quadratic or cubic into
the datasheets graph.
3)do your own calibrated measurements
