PROBLEM TO BE SOLVED: To provide a remote measurement apparatus capable of continuously implementing sensing or measurement by supplying stable power while using a fuel cell even under such a condition that a power generation amount is reduced in a power generation device utilizing natural energy.SOLUTION: The measurement apparatus includes: (A) a sensing device or a measuring device; (B) a device for integrating results outputted from the sensing device or the measuring device; (C) a device for transmitting integrated output of the device to a remote site; and (D) a power supply which supplies power to the devices (A)-(C) and is formed from a fuel cell and a secondary battery. In the case where an operation voltage of one of the devices (A)-(C) is narrower than a fluctuation range of a voltage supplied by the power supply (D), a device including a voltage stabilization function is connected between the power supply (D) and the devices (A)-(C) or in the case where the operation voltage is out of a range of the supply voltage, a device including a function for regulating the supply voltage of the power supply (D) into the operation voltage of the devices (A)-(C) is connected, such that suitable power can be supplied to the devices (A)-(C). |
