Soil Moisture Temperature
TerraSense SMT2
› Soil moisture and temperature sensor
Parameters under measurement:
- Soil Water volume content (WVC) (WVC)
- Soil temperature
- MeteoSense base station/MeteoSense PRO
- AgriSense/VineSense
- Wireless unit AgriSense/VineSense
- HandySense reader.
- PS-0050-JB - Digital RS485 interface
- PS-0081-GE - Analog voltage output
- Means of operation
The TerraSense SMT2 sensor carries out the water volume content measurement, by measuring the soil dielectric constant.
The specific implementation features make the sensor insensitive to soil temperature and conductivity variations.
Furthermore, the internal analysis algorithms and the digital output allow high accuracy with all soil kinds, thus not requiring manual calibration.
