EXTREMELY ROBUST AND RELIABLE ACOUSTIC RAIN SENSOR

The RHD is a low-cost, high precision and ultra-robust rain sensor. It features very low-power consumption, is maintenance-free and has a completely sealed acoustic detector with no moving parts. The sensing device is a polished stainless steel hemisphere supported by a strong stainless steel arm. It detects changes of the acoustic pressure that are induced by the impact of raindrops or hailstones. The RHD also includes a distrometer that returns the drop size distribution.
