<P>PROBLEM TO BE SOLVED: To provide a sensor terminal device capable of efficiently transferring each measurement data from the sensor terminal device having a plurality kinds of sensors to a server while utilizing limited radio band resources. <P>SOLUTION: A sensor terminal device digitizes measurement data input from a sensor and stores the measurement data in a memory, configures the measurement data stored in the memory as a radio frame, and transmits the radio frame by radio to a server collecting the measurement data. The sensor terminal device comprises measurement data transmission means for monitoring the stored data amount in the memory, and transmitting a radio frame which accommodates the measurement data stored in the memory in a lump when the stored data amount has reached the maximum data size capable of being transmitted as the radio frame. <P>COPYRIGHT: (C)2013,JPO&INPIT |
