SENSOR DEVICE WITH SAMPLING FUNCTION, AND SENSOR DATA PROCESSING SYSTEM USING SAME

A sensor device allows a ratio of measurement intervals to be arbitrarily set and held among multiple sensor devices and can perform autonomous measurements while holding the set ratio of measurement intervals. The sensor device includes: a counter (511) for counting the number of count commands used to perform measurements while maintaining among multiple sensor devices the ratio of measurement intervals; a ratio-of-measurement-interval-holding-unit (512) for setting the ratio of measurement intervals to a desired ratio of measurement intervals and holding respective values of the ratio of measurement intervals for each of the multiple sensor devices; a sampling-timing-generating-unit (513) for receiving a count value of the counter (511) and the setting value of the ratio of measurement interval which is held by the ratio-of-measurement-interval-holding-unit (512), and for generating a sampling timing signal based on the comparison result between the count value and the setting value; and a sampling-unit (515) for sampling a detection signal detected by the detecting unit (514), by using the sampling timing signal generated by the sampling-timing-generating-unit (513).
