I. Principles of Imported Soil Pressure Sensors Principles of Imported Soil Pressure Sensors

Soil pressure sensors, as the name suggests, are sensors used to measure soil pressure. Their working principle is mainly based on strain gauge technology, piezoelectric effect, or capacitive sensing technology.

1. Strain Gauge Technology Strain gauges are sensitive components that convert mechanical strain into electrical signals. When soil pressure acts on the sensor, the strain gauges inside the sensor deform, thereby changing their resistance value. By measuring the change in resistance, the pressure received can be calculated.

2. Piezoelectric Effect Some materials generate electric charges when subjected to mechanical pressure; this phenomenon is called the piezoelectric effect. Piezoelectric soil pressure sensors utilize this principle to convert soil pressure into electrical signals for measurement.

3. Capacitive Sensing Technology Capacitive sensors perceive pressure by measuring changes in capacitance. When soil pressure acts on the sensor, the capacitance value inside the sensor changes, which is converted into a corresponding electrical signal through a circuit.
