PROBLEM TO BE SOLVED: To provide a method of converting a measurement value of a thermosensitive resistor element that can measure a wind velocity at a high speed into a wind velocity at a high speed.;SOLUTION: The wind velocity sensor system 10 includes a wind velocity sensor 20 having a first thermosensitive resistor element 21a having a sensitivity to a wind velocity and a second thermosensitive resistor element 21b having a sensitivity to a temperature. The wind velocity sensor system 10 further includes a computer 40 that converts a measurement value of the thermosensitive resistor element by using a measurement value converting formula having a first elementary function f1 using a measurement value V1 of the first thermosensitive resistor element 21a as an independent variable and a second elementary function f2 using a measurement value V2 of the second thermosensitive resistor element 21b as an independent variable. In addition, the wind velocity sensor system 10 further includes a drive detection circuit part 30 that drives the first thermosensitive resistor element 21a to heat it to a temperature higher than a room temperature, outputs the measurement value V1 based on a resistance value of the first thermosensitive resistor element 21a, drives the second thermosensitive resistor element 21b and outputs the measurement value V2 based on a resistance value of the second thermosensitive resistor element 21b.;COPYRIGHT: (C)2011,JPO&INPIT
