Soil Humidity Flash Meter ABS Build

Ultra-lightweight (12 g) and compact (155 × 26 × 24 mm), this soil moisture sensor is crafted from durable ABS plastic — chosen for dimensional stability, low moisture absorption, and resilience to indoor environmental fluctuations. It operates using two included LR44 batteries (1.5 V), enabling instant deployment. Dual-mode functionality includes manual trigger for precise moment-of-use readings and automatic mode for periodic assessment. A dedicated LED delivers immediate visual feedback via flash timing — no interpretation of numerical scales needed. Designed for frequent use across diverse indoor planting scenarios: from office desk succulents to conservatory ferns, balcony herbs, and educational plant labs.
