Soil Sensors

Moisture Sensors: Perhaps the most widely used type, moisture sensors detect the amount of water present in the soil. They work by measuring the dielectric constant or the resistance between two electrodes, which changes with varying moisture levels.

Temperature Sensors: Essential for understanding the thermal environment of crops, these sensors track soil temperature, an important factor affecting seed germination, root growth, and microbial activity.

Electrical Conductivity (EC) Sensors: EC sensors assess the salinity and overall nutrient availability in the soil. Higher EC values typically indicate a greater concentration of dissolved salts, which can be detrimental if too high.

pH Sensors: Measuring the acidity or alkalinity of the soil, pH sensors are critical for determining the suitability of the soil for specific crops, as different plants thrive in different pH ranges.
