Wireless data transmission strain gauge

A strain gauge for wireless data transmission comprises a power supply module, a single-chip microcomputer module, a GPRS module, a linear adjustable resistor, a fixing mechanism, a detection circuit and a receiving circuit. Each fixing mechanism comprises a shell and a magnet, the magnet is mounted on the outer side of the shell, the linear adjustable resistor is mounted outside the front end of the shell of one fixing mechanism, a connecting rod is mounted at the front side end of the other fixing mechanism, and the other end of the connecting rod and the front end of an adjustable handle of the linear adjustable resistor are mounted together; the power module, the single-chip microcomputer module, the GPRS module and the detection circuit are installed in a shell of one fixing mechanism and electrically connected, and the receiving circuit is installed in a working equipment electric cabinet. When the spandrel girder deforms, remote personnel can understand specific data, meanwhile, the buzzer sounds to pr
