A precipitation gauge for measuring liquid and frozen precipitation is
provided according to the present invention that includes a support
structure having at least one light sensor, or pair of electrodes, and at
least one light source disposed thereon so that the light sensor may
receive light that is emitted from the light source. The light sensor or
light sensors and the light source or light sources generally extend a
substantial height of the support structure. The light sensor or light
sensors generate an output signal in response to the amount of light
received from the light source. A microprocessor receives the output
signal or output signals from the light sensor or light sensors and
determines whether precipitation is present between the light sensor or
light sensors and the light source or light sources. Based on the output
signal or output signals, the microprocessor determines and displays the
level of precipitation. The microprocessor may also determine the density
of frozen precipitation.
