ABSTRACT:
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.
