<P>PROBLEM TO BE SOLVED: To provide a low cost and less power consuming radio sensor. <P>SOLUTION: A CPU 3 for measurement, every when creating measured data, compares current measured data and measured data stored in a memory M 2 which is previously determined to be radio transmitted, and determines the current measured data to be radio transmitted if the current measured data becomes greater than a predetermined value, then notifies to a CPU 4 for transmission. The CPU 3 renews and stores the measured data to be radio transmitted in the memory M 2 as the transmission measured data, and uses it as the data being previously determined to be radio transmitted when comparing with next measured data. <P>COPYRIGHT: (C)2008,JPO&INPIT |
