Abstract
PURPOSE: To make possible to reduce the size and weight of a measuring unit and carry out high accuracy measurement by accumulating the data about a duration of sunshine in an electric current integrating module which constitutes the measuring unit.
CONSTITUTION: With a changeover switch 40 turned to a solar cell 10 side, a measuring unit MU is placed at a position to measure the duration of sunshine. The quantity of silver ions corresponding to the duration of sunshine and the state of sunshine is accumulated in a center electrode 20k. Next, the changeover switch 40 is changed to a time measuring circuit 80 side. Time for passing the electric current to a module 20 by a constant current source 70 is measured by the time measuring circuit 80 which stops time measuring by breaking the current when the module 20 has come to be a clear state. From the value of the time measuring circuit 80, the state of sunshine is measured.
