Smart sensors: the key to more efficient farming

Modern agriculture faces the challenge of feeding a constantly growing world population in a sustainable and efficient manner. In this context, smart sensors emerge as a fundamental tool to optimize cultivation processes and increase productivity.

Smart sensors collect real-time data on various key plant growth parameters such as soil moisture, temperature, sunlight, pest and disease presence. This accurate information enables farmers to make informed and timely decisions to optimize irrigation, fertilization, pest control and other agricultural practices.

By analysing the data provided by the sensors, farmers can adapt cultivation strategies to the specific needs of each plant and each area of ​​the field. This allows for more efficient use of resources such as water, fertilisers and pesticides, reducing costs and minimising environmental impact.

Early detection of pests, diseases and adverse environmental conditions using smart sensors enables farmers to take preventive measures and avoid significant crop losses. Sensor-driven smart agriculture contributes to more sustainable agricultural production.

Among the most common types of smart sensors are:

• Humidity of floor: They monitor water content and help plan irrigation efficiently.
• Ambient temperature and humidity: They allow us to know the exact climatic conditions, improving decision-making.
• Nutrients: They analyze the composition of the soil to determine the need for fertilizers.
• Light: They evaluate the available light and suggest adjustments to maximize photosynthesis.

These sensors integrate advanced technologies such as IoT and Big Data.

Evolution of sensor technology in the agricultural sector

Sensor technology has advanced significantly in recent decades, boosting agricultural efficiency. Initially, sensors were simple devices for measuring soil moisture and temperature. Over time, more sophisticated sensors have been developed that are capable of:
