The index relationship between humidity sensitive resistance value and temperature is discovered by analyzing the characteristic of humidity sensitive resistor.Hardware compensation is completed through additional logarithm operation circuit

it is deviated from index state and the lower humidity performance is improved.The sudy and analysis of the charecter is based on macromolecule humicap sensor EE06 humidity which carry out temperature compensation adopted mathematical model fitting software arithmetic above and below 0 ℃ respectively

it made the significance of hygrometic equation of the humidity sensitive unit at 5 668.579 0 and 2 416.919 00 greater than F0.01（9

8）

and is highly distinctive at 0.01 significance level.Both temperature compensation methods greatly improve the humidity measuring accuracy of the humidity sensor.
