Four-sensor sunshine recorder
Although it is almost impossible to imagine present-day meteorology without electronic equipment, sunshine is still widely measured with the aid of the classic, all-mechanical, Campbell-Stokes recorder. The electronic instrument described in this article offers far better accuracy than the Campbell-Stokes meter. It measures the total time during which sunshine is detected, and records this information with the aid of a computer.
