TR02Soil Monitoring
SDI-12 Soil Moisture, EC & Temperature Sensor
SDI-12 soil sensor measuring soil moisture content, temperature and optionally electrical conductivity (EC). Soil moisture is measured as apparent dielectric permittivity εa with range 1–81 and accuracy ±1 εa from 1.00 to 40.00; temperature range is -40 to 80°C with ±0.5°C accuracy; EC range is 0–23 ds/m. Typical applications include scientific research, irrigation, greenhouse and smart agriculture.
