916–924 MHz
Measurement Range: In soil: 0 to 0.570 m³/m³ (volumetric water content)
Extended Range: -0.659 to 0.6026 m³/m³
Accuracy: ±0.033 m³/m³ (±3.3%) typical 0 to 50°C (32° to 122°F) for mineral soils
up to 10 dS/m and ±0.020 m³/m³; (±2%) with soil specific calibration
Resolution: 0.0008 m³/m³ (0.08%)
Volume of Influence: 1 liter (33.81 oz)
Sensor Frequency: 70 MHz
Sensor Operation Temperature Range: 0° to 50°C (32° to 122°F). Although the sensor probe and cable can safely operate at below-freezing temperatures (to -40°C/F), the soil moisture data collected at these extreme temperatures is outside of the sensor’s accurate measurement range. Extended temperatures above 50°C (122°F) will decrease mote battery life.
