Onset S-SMD-M005 10HS Soil Moisture Smart Sensor (0~0.570 m³/m³)

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 

Soil Probe Dimensions: 160 x 32 x 2 mm (6.5 x 1.25 x 0.08 in.) 

Weight: 190 grams (6.7 oz) 

Sensor Operating Temperature: 

  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) and the smart sensor adapter housing (the portion of the sensor cable that houses the electronics) can be exposed to temperatures up to 70°C (158°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 logger battery life. 

Bits per Sample: 12 

Number of Data Channels: 1 

Cable Length Available: 5 m (16 ft) 

Length of Smart Sensor Network Cable: 0.5 m (1.6 ft)

Item included: protective cap
