Description

The Seeed Studio S-Soil MT-02A is an industrial-grade sensor designed to provide critical data for precision irrigation and environmental monitoring. By measuring the dielectric constant of the soil, it delivers stable Volumetric Water Content (VWC) readings across various soil types, alongside accurate temperature data. Housed in a robust, anti-corrosion, and flame-retardant epoxy resin with food-grade stainless steel probes, the MT-02A is built to withstand long-term burial in harsh outdoor environments.

Technical Intelligence

High Stability Advanced signal processing ensures high reliability even in soils with varying salinity and texture.
Rugged Protection IP68 rated for permanent immersion and burial, with reverse voltage and anti-corrosion features.

Professional Use Cases

• Smart Agriculture: Optimize irrigation schedules based on real-time root-zone moisture levels.
• Greenhouse Monitoring: Maintain ideal growing conditions through integrated temperature and humidity control.
• Scientific Research: Conduct long-term hydrological and soil health studies with research-grade accuracy.
