Continuous Measurement System Design of Soil Mechanical Resistance Based on Arduino

The soil mechanical resistance affected crop yields，agricultural machinery performance and power consumption.In order to achieve continuous measurement of soil mechanical resistance，a continuous measurement was designed and tested with sensor，the system measured soil mechanical resistance by “S” type force transducer，measured the distance by ultrasonic ranging module and measured the location and speed with GPS module，at the same time，all the measured data was stored to the SD card module through the Arduino program control.The system was feasibility and accuracy through simulated by Proteus and connected hardware.Measurement processes and methods of the system were consistent with the precision agriculture′s requirements.
