PROBLEM TO BE SOLVED: To perform conversion processing from a detection value to a measurement value, while taking into consideration the characteristic dispersion of a radio sensor device. SOLUTION: This wireless sensor device comprises at least one sensor 101, a signal processing part 190 for converting a detection value S<SB>1</SB>of the sensor 101 to a measurement value S<SB>3</SB>, by assigning it to an approximation; and a transmission circuit part 141 for wirelessly transmitting the measurement value S<SB>3</SB>. The signal processing part 190 refers to flags 131-133 for storing the characteristics of the sensor 101 and performs conversion by using a different approximation according to them. Since the measured value S3 is calculated, by performing conversion using different approximations according to the characteristics of the sensor 101, accurate measurement can be performed, even in the case of using a sensor, having a large dispersion such as a humidity sensor.
