<p>PROBLEM TO BE SOLVED: To provide a sensor system capable of saving time and labor for maintenance control.SOLUTION: A sensor system 1 includes: a generator 11; a first switch section 14; a second switch section 17; a third switch section 18; a sensor section 20; a power supply source 16; and a control section 23. The first switch section 14 is connected in rear of the generator 11 and set open in an initial state. The second switch section 17 is connected in rear of the power supply source 16 and short-circuited in an initial state. The third switch section 18 is connected in rear of the second switch section 17 and set open in an initial state. Electric power is supplied from the generator 11 or the power supply source 16 to the sensor section 20, a wireless communication section, and the control section 23. The electric power is supplied to the control section 23 from the power supply source 16 in the initial state. If the electric power obtained by the generator 11 is equal to or higher than a predetermined level, the control section 23 controls the second switch section 17 to be set open. In this case, the first switch section 14 is short-circuited.</p> |
