Understanding Soil Moisture Sensor Working Principle: A Comprehensive Guide

Soil moisture sensors are vital tools in modern agriculture and environmental monitoring. These devices measure the water content in soil, helping optimize irrigation, conserve water, and improve crop yields. In this guide, we’ll explore the soil moisture sensor working principle, types, and applications.

How Soil Moisture Sensors Work

Most soil moisture sensors operate based on capacitance or resistance principles. Capacitive sensors measure the dielectric constant of soil, which changes with water content, while resistive sensors detect electrical conductivity between probes.
