PROBLEM TO BE SOLVED: To provide a vibration sensor system capable of transmitting vibration data acquired by measuring vibrations of an object to be measured to the outside by a wireless transmission means even if the vibrational energy of the object to be measured does not exceed a prescribed threshold value and observing a dynamic state such as the extent of increases of vibrations of the object to be measured even after its vibrational energy has exceeded the threshold value. SOLUTION: The vibration sensor system is provided with a control module 17. According to the intensity (electric power generated by a vibration-to-electric power generator module 14) of vibrations of an external wall part 2, the control module 17 changes both the number of times of the conversion of the vibrational energy of the external wall part 2 of a device 3 to be measured into electric power by the vibration-to-electric power generator module 14 and the detection of electric power generated by the vibration-to-electric power generator module 14 by a voltage sensor module 15 and the number of times of the transmission of vibration data indicating the intensity (electric power generated by the vibration-to-electric power generator module 14) of vibrations of the external wall part 2 by the wireless transmission module 18.
