PROBLEM TO BE SOLVED: To provide a vibration power generator wireless sensor capable of continuously collecting and transmitting meteorological information by stably supplying electric power using no power supply cable, which is disposed at every point where meteorological information is collected.SOLUTION: The vibration power generator wireless sensor includes: a vibration power generator (10) and control circuit sections (21, 22). The vibration power generator (10) has a permanent magnet and a coil which is dispose and fixed being separated at a distance from the periphery of the permanent magnet, which is disposed on a structure as a vibration source. The control circuit sections (21, 22) are driven using an electric power generated by the vibration power generator and each of which repeats an activated state and a sleep state at a predetermined period. Each of the control circuit sections (21, 22) collects a meteorological data from an external meteorological sensor at every period of the activated state. Determining that the electric power generated by the vibration power generator and stored satisfactorily secures an amount required for radio transmitting the collected meteorological data, the control circuit sections (21, 22) performs a radio transmission of the collected meteorological data. |
