The single point sensor is 10.5cm (4”) in size and can measure soil moisture + temperature or soil moisture + temperature + salinity. The sensor can be completely buried in the soil. Unlike other single point sensors, the sensor measures volumetric water content for the length of the sensor. Sentek has developed, and continues to develop, a number of soil specific calibrations that can be applied to the data to help you make sense of the readings. Two cabling options are available, one where the cable exits from the side of the unit, and the other where the cable exits out the top of the unit.
Currently available with the SDI-12 protocol, with applications including (but not limited to) turf, nursery, greenhouse, planted rooftops, mushroom (and truffle!) production, satellite cross-calibration and leachate monitoring
