PROBLEM TO BE SOLVED: To provide a remote strain sensor system more excellent in continuous measurement than in the past for a civil engineering structure or the like. SOLUTION: The remote strain sensor system includes a plurality of sensor devices, and a relay machine controlling information by relaying communications between the plurality of sensor device and a host device. The strain sensor device includes a strain gauge, a bridge circuit for fetching a measurement signal, an A/D converter for converting it to a digital value, and a radio device for transmitting data to a CPU for processing the data, and adapted to be directly fixable to the civil engineering structure or the like through a magnet or adhesive.
