Design, Manufacturing, and Calibration of a Conductivity Sensor for Precision Agriculture

The research describes the development of an IoT device for collecting data on a crop soil, particularly electrical conductivity. Field tests were conducted in two different types of soils: rice crops in Tolima and coffee and Liriope crops in Cundinamarca. The device’s results were compared with commercial equipment and physicochemical laboratories, demonstrating its effectiveness and accuracy. The development of the device arises from the interest in improving soil health, which is crucial for productivity in agriculture given current growing population.
