Rain Rate — 5-Minute Resolution (in/hr)
⚠ Sensor Divergence: Tipping bucket registers 0.56" vs. piezo at 0.32" (1.75× ratio). Light/intermittent rain at 0.02–0.05 in/hr disproportionately inflates the tipping bucket—individual tips may be double-counted during low-rate drizzle. The piezoelectric signal is generally considered more accurate in light rain conditions.
