Sensor System for Continuous Real-Time Measurement of Soil Mechanical and Physical Properties

The System of Sensors for continuous and real-time measurement of soil strength utilizes an electronic circuit based on the Arduino Mega 2560. The setup includes an alphanumeric display, a keypad, a conditioning circuit for strain gauges, a Bluetooth module, two 2.4GHz RF Modules, two pressure sensors, four distance sensors, an electrical soil conductivity sensor, two rotation speed sensors, and a GPS unit. These components interface with an Android application designed to manage all calculations and decision-making processes. This system is mounted on a two-wheel drive tractor and employs mathematical models developed by researchers to link cone index, slip, and drawbar pull. The real-time data gathered provides valuable insights into soil conditions, significantly enhancing precision agriculture operations.
