Soil health is a crucial factor in sustainable agriculture and environmental conservation. Monitoring soil health allows farmers, researchers, and environmentalists to understand the status of soil fertility, nutrient availability, and potential contaminants. Soil sensors play a pivotal role in this process, providing real-time data on soil conditions and enabling precise decision-making.

Soil sensors are devices capable of measuring various soil parameters such as moisture content, temperature, pH, and nutrient levels. These sensors are designed to be placed directly in the soil, either manually or through automated systems, to collect accurate and representative data.

One of the key applications of soil sensors is in precision agriculture. By monitoring soil conditions in different areas of a field, farmers can adjust their crop management practices accordingly. For instance, if a sensor detects low moisture levels in a particular area, farmers can target that area with additional irrigation to optimize crop growth. Similarly, by monitoring nutrient levels, farmers can apply fertilizers more efficiently, reducing waste and environmental pollution.
