I've looked at the Dynon Wiki on sensor definitions and while initially it sounds a little complicated, in actual practice with a little help from Dynon, I don't think it would be that bad to develop a custom sensor file. I think it would be great if Dynon would put together a step by step example of creating a typical sensor file. If I've got the steps right you would:
1) Gather data about the sensor; e.g. a resistive temperature sensor would be placed in ice water and the resistance value recorded, then several more points up to the boiling point of water. I think you need at least five or six different data points to develop the fourth order polynomial that defines the sensor, the more the better.
2) Use a regression analysis program such as CadreReg (freeware available from CadrePro FEA) to develop the polynomial.
3) enter this polynomial into the sensor file and fill out the other simple parameters and you're done.
As long as you can measure the data points and enter them into CadreReg, you really don't have to understand how to develop the fourth order equation.
I'm not sure if you have to plot Temp (or whatever) against resistance or if it needs to be plotted against voltage. A quick tutorial from Dynon would clarify this. Of course, it's also possible that I'm completely full of it.
The best thing would be if dynon would give us a quick walk through on developing a simple sensor.
