To provide a sensor device having a function for suppressing an abnormal output of measurement data acquired from a humidity sensor.

This device is equipped with the humidity sensor, a temperature sensor, and a low-pass filter for filtering and outputting the measurement data acquired from the humidity sensor. When the variation per prescribed time of the temperature acquired by the temperature sensor is large, the time constant of the low-pass filter is set large, and when the temperature variation is small, the time constant of the low-pass filter is set small.
