Contact Us Rain Detector DRD11A Rain intensity measurement with processing unit Rain and snow are quickly and accurately detected with the DRD11A rain detector. It 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. + Show more Key Benefits An internal heating element Ensures that the detection surface dries quickly. An essential factor in calculating intensity. A special delay circuitry Allows about two-minute interval between raindrops before assuming an OFF (no rain) position. Reliable droplet detection Sensor performance is not affected by reasonable amounts of dirt and dust.
