Cactus Whisper

Precision IoT hydration monitoring for arid flora: Cactus Whisper uses capacitive sensors to eliminate root rot in high-value succulents.

The CW-1 hardware module integrates a 3-pin capacitive probe with a low-power Bluetooth 5.0 radio. It tracks three critical metrics: volumetric water content (VWC), ambient temperature, and light intensity (LUX). Users receive push notifications via the Whisper App (iOS and Android) when VWC drops below the 5 percent threshold for species like Echinocactus grusonii. The system runs for 18 months on a single CR2032 battery. It eliminates the guesswork that kills 40 percent of indoor succulents annually.
