| titleOfInvention | A kind of soil moisture sensor based on the detection of RC charge and discharge peak-to-peak value |
| abstract | The present invention relates to a kind of soil moisture sensors based on the detection of RC charge and discharge peak-to-peak value, square wave excitation signal source circuit, precision resistance R, electric discharge Schottky diode D, capacitance probe C, DC isolation circuit, peak-to-peak value detection circuit and diode drop compensation circuit including pressure stabilizing source circuit, for generating square-wave signal.The beneficial effects of the present invention are: having source of stable pressure, the working method that high frequency square wave motivates lower RC circuit charging battery to discharge fastly, transducer sensitivity is effectively increased, solves influence of the soil ion polarization additional capacitor to sensor, i.e., soil salt is on the problems such as sensor influence；The exploitation of the simple and convenient secondary meter of sensor input/output interface；The soil moisture sensor structure is simple, easy to make. |
