Abstract:
1. A sensor interface device comprising: a sealed sensor body; a battery disposed within said sealed sensor body; a wireless transceiver communication device disposed in said sealed sensor body and configured for intermittent communication of the following conditions: soil moisture, temperature, and salinity; a first sensor cable interfaced with circuitry within said sealed sensor body; said first sensor cable having a first end sealed to an external surface of said sealed sensor body and a second end configured for sensing soil temperature, capacitance and soil conductivity; a second sensor cable interfaced with said circuitry within said sealed sensor body; said second cable having a first end sealed to said external surface of said sealed sensor body and a second end configured for sensing soil temperature, soil capacitance and soil conductivity; said first and second sensor cables configured to prevent moisture penetration within said first and second sensor cable while buried within soil; wherein said soil sensor provides soil moisture data, soil temperature data and soil salinity data which are cross compensated.
