 [. . . ] DRD11A RAIN DETECTOR

· Fast and accurate precipitation detection (ON/OFF) · Rain intensity measurement with processing unit · Maintenance free · Heating element for keeping sensor free of snow and condensed moisture,  and for quick drying area on the sensor plate,  rain intensity has a direct impact on the amplitude and variation of this analog signal.  [. . . ] The DRD11L is a low heating power model of the DRD11A. It is intended to be used in areas with only rain or wet/moist snow precipitation. 

Rain and snow are quickly and accurately detected with the DRD11A Rain Detector. The DRD11A operates via droplet detection rather than by signal level threshold. A special delay circuitry allows about two-minute interval between raindrops before assuming an OFF (no rain) position. This enables the sensor to accurately distinguish between rain cessation and light rain. The DRD11A also features an analog Rain Signal for estimating rain intensity. Since this signal is proportional to the percentage of moist or wet
