PROBLEM TO BE SOLVED: To provide a radio data monitoring system capable of managing in an optimal radio wave condition without requiring a fine control of a transmission output of a sensor by a system administrator when a use environment changes during the use of a network, and capable of assuring a stable operation of the wireless network and a long life time of a battery.SOLUTION: The radio data monitoring system includes: a base station; a sensor operating with a battery, periodically measuring data to radio-transmit the measured data to the base station; a radio network system including a relay unit for relaying a radio communication path between the base station and the sensor; and a monitoring operation terminal connected to the base station by radio or wired method and monitoring the measured data. The sensor includes a storing means for recording the measured data, and radio network communication information as the information related to the transmission and reception between the base station and the sensor. |
