Hi,Campbell sir
We have thermistor and CR1000.
How Equipment installation and program?
thank.
thermistor date
(Resistance R)--(Temperature Y)
62914.65----------- 20
50000 --------------25
39929.51------------30
32037.72------------35
25823.38------------40

Do you got the coefficients for that thermistor (A,B,C) so you can use the Steinhart-Hart equation with the voltages that should come out of a measurement with that thermistor?
See datasheet for Soil Temp Probe 107 for example (page 9).
For even better help, post the type/name of that thermistor you got there.
If you cannot find the Steinhart-Hart parameters please give resistance vs temperature for the lowest and highest temperatures you are interested in plus the resistance for the temperature half way between the extremes.
I have a 2008 STM2500 dual sensor.
They publish the thermistor R at:
-15C = 71172
25C = 10000
65C = 2128
How does one calculate the Steinhart-Hart parameters from this?
