<P>PROBLEM TO BE SOLVED: To provide a radio sensor system for accurately performing data communication between a sensor station and an external station while suppressing the increase of power consumption. <P>SOLUTION: This radio sensor system is configured of a sensor station which carries out the sampling of a sensor signal, and transmits the sampled sensor data by radio; and an external station which receives the sensor data transmitted from the sensor station. A gain adjustment packet for adjusting receiving sensitivity is attached to the front part of the main body section of data to be transmitted so that radio data transmission between a sensor station and an external station can be performed, and when an NACK signal showing the generation of a communication error is received, the number of gain adjustment packets is increased according to a communication error frequency err, and the radio data transmission is retried. <P>COPYRIGHT: (C)2009,JPO&INPIT |
