設した光雨量計測装置。Every time a unit amount of rainfall accumulates in a measuring cell that measures the amount of rainfall per unit, the horizontal rod to which the measuring cell is fixed tilts, and an electric switch attached to the horizontal rod is activated and energized by a battery. An optical rainfall pulse corresponding to the unit rainfall is generated from an electrical/optical converter, and the optical rainfall pulse is supplied to the optical/electrical converter via an optical cable for avoiding the influence of induced lightning, and the converted electrical signal pulse is used to calculate the rainfall. In an optical rainfall measuring device that displays rainfall by operating a counting circuit, a battery voltage drop detection circuit is installed in parallel at the end of the series circuit element of the battery and the electric switch, and the optical rainfall pulse width is connected to the battery voltage drop detection circuit. A control circuit energizes a control switch in series with the electrical switch to change the duration of the electrical signal pulse supplied to the electrical/optical converter from the operating duration of the electrical switch when the battery voltage is low. Optical rainfall measurement device that is small and attached to the output side of an optical/electrical converter by sequentially connecting a pulse width detection circuit and a battery voltage drop indicator in cascade.
