TBSST04 SDI-12 Soil Temperature Probe

Soil Temperature Probe

TBSST04 is a soil temperature sensor with SDI-12 interface. It allows measuring the temperature on 3 different depth levels (up to 3 meters for each segment). The product is available in 3 variants, with one, two or three temperature sensors. The sensor is used to monitor the soil temperature and for specific applications like compost temperature monitoring where this parameter is critical to prevent sudden fire.
