Application

Tips: How does the analog soil moisture sensor use the TDR method for measuring soil moisture?

The analog soil moisture humidity utilizes Time-Domain Reflectometry (TDR) technology to measure soil moisture content. TDR works by sending an electrical pulse along a probe inserted into the soil. As the pulse travels, it interacts with the soil moisture, causing changes in the signal's reflection time. The sensor calculates moisture content based on these reflections, as the presence of water in soil affects the dielectric properties and thus the speed of the pulse. This method provides high accuracy, is less affected by soil salinity, and is reliable for various soil types, making TDR an industry-preferred choice for precise soil moisture monitoring.
