How is TDT⁵ different from traditional soil moisture sensors?
TDT⁵ uses Time Domain Transmissometry with a five times longer effective antenna length and multi-depth measurement segments. This allows it to measure moisture across the full soil profile instead of at a single point. The result is higher accuracy, better stability, and a clearer understanding of how water moves through the soil.
Does TDT⁵ require calibration for different soil types?
TDT⁵ is designed to perform consistently across a wide range of soil types with minimal calibration. Unlike capacitance sensors, it does not require frequent soil-specific recalibration and maintains stable readings over long-term deployments, even in clay-rich or saline soils.
How deep can TDT⁵ measure soil moisture?

How does TDT⁵ perform in saline or clay-heavy soils?
TDT⁵ maintains accurate and repeatable measurements in saline and clay-rich soils where other technologies often fail. Its measurement approach is less sensitive to electrical conductivity, reducing signal distortion and long-term drift in challenging soil conditions.
Can TDT⁵ be integrated with existing data loggers or IoT systems?
