Description

The Seeed Studio S-YM-01 is an enterprise-grade leaf wetness and temperature sensor engineered for critical agricultural and research applications. By mimicking the thermal resistance, shape, and thickness of a real leaf, the sensor provides accurate data on the percentage of water, ice, or fog covering the foliage. This precision instrument is essential for managing irrigation, preventing bacterial outbreaks, and optimizing foliage spraying in greenhouses and smart farms.

Professional Environmental Intelligence

Biomimetic Sensing Designed to sense shape and thickness to accurately replicate the thermal characteristics of real plant leaves.
Industrial Grade Protection Fully sealed with flame-retardant epoxy resin and IP68 rated to withstand permanent outdoor immersion.
Circuit Reliability Features built-in TVS/ESD protection and reverse power protection for secure field deployment[cite: 3177].

Key Use Cases

Smart Agriculture: Automate irrigation and detect frost or fog conditions in real-time.
Disease Prevention: Monitor leaf moisture duration to predict and mitigate the risk of bacteria and fungi.
Precision Research: Conduct high-accuracy scientific studies on plant thermal resistance and leaf wetness dynamics.
