TBSST03 SDI-12 Soil Temperature Probe
Soil Temperature Probe
TBSST03 is a soil temperature sensor with SDI-12 interface that can operate over a wide temperature range. The electronic parts are mounted inside an UV resistant resin/glass fiber fabrics reinforced tube and the sensors are based on Swiss made PT1000 with 0.1 ̊C accuracy. The sensor is typically used to measure the temperature in situations where probing is difficult like in boreholes or soil trenches.
