Abstract:
There is provided a solar powered light intensity measurement device which includes one or more photovoltaic cells, one or more resistors and one or more light emitting diodes. The one or more photovoltaic cells convert light to electricity, the output corresponding to the intensity of incident light. Electrically activated from the photovoltaic cells, through the one or more resistors, the light emitting diodes emit a signal color, further corresponding to their electrical activation and hence to the intensity of light incident upon the one or more photovoltaic cells. The signal color is compared to reference color or chart for use in determining the relevant light intensity. In one embodiment, the device further includes an analog switch.
