The HOBOnet Wireless Soil Moisture Sensor integrates the field-proven ECH2O™ EC5 Sensor and provides readings directly in volumetric water content.

The sensor's high-frequency design minimizes sensitivity to salinity and textural effects, and gives it a wide measurement range. HOBOnet Wireless Sensors communicate data directly to the RX3000 weather station or pass data through other wireless sensors back to the central station. They are preconfigured and ready to deploy, and data is accessed through HOBOlink, Onset’s innovative cloud-based software platform.

Sensor Features

  • ±3% accuracy in typical soil conditions, and ±2% accuracy with soil-specific calibration
  • Measures a 0.3-liter volume of soil for taking readings at a specific depth or in a container
  • High-frequency (70 MHz) circuit provides good accuracy even in high-salinity and sandy soils.

Wireless Features

  • 900 MHz wireless mesh self-healing technology
  • 450 to 600 meter (1,500 to 2,000 feet) wireless range and up to five hops
  • Up to 50 wireless sensors per RX3000
  • Simple button-push to join the HOBOnet wireless network
  • Onboard memory to ensure no data loss
  • Powered by rechargeable AA batteries and built-in solar panel.

Note: A complete HOBOnet system requires at least one HOBO RX3000 Remote Monitoring Station, a HOBOnet Wireless Manager, and a HOBOnet Wireless Sensor. HOBOnet Wireless Repeaters can be added to extend the range.

Explanation

Sensor

Measurement Range

In soil: 0 to 0.550 m³/m³ (volumetric water content)

Extended Range

-0.401 to 2.574 m³/m³

Accuracy

±0.031 m³/m³ (±3.1%) typical 0 to 50°C (32° to 122°F) for mineral soils up to 8 dS/m and ±0.020 m³/m³ (±2%) with soil specific calibration; see Notes 2 and 3

Resolution

0.0007 m³/m³ (0.07%)

Volume of Influence

0.3 liters (10.14 oz)

Sensor Frequency

 

70 MHz

Sensor Operating 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.

Wireless Mote

Operating Temperature Range

-25° to 60°C (-13° to 140°F) with rechargeable batteries
-40 to 70°C (-40 to 158°F) with lithium batteries

Radio Power

12.6 mW (+11 dBm) non-adjustable

Transmission Range

Reliable connection to 457.2 m (1,500 ft) line of sight at 1.8 m (6 ft) high
Reliable connection to 609.6 m (2,000 ft) line of sight at 3 m (10 ft) high

Wireless Data Standard

IEEE 802.15.4

Radio Operating Frequencies

RXW-SMC-900: 904–924 MHz
RXW-SMC-868: 866.5 MHz
RXW-SMC-922: 916–924 MHz

Modulation Employed

OQPSK (Offset Quadrature Phase Shift Keying)

Data Rate

Up to 250 kbps, non-adjustable

Duty Cycle

<1%

Maximum Number of Motes

50 motes per one RX Wireless Sensor Network

Battery Type/ Power Source

Two AA 1.2 V rechargeable NiMH batteries powered by built-in solar panel or two AA 1.5 V lithium batteries for operating conditions of -40 to 70°C (-40 to 158°F)

Battery Life

With NiMH batteries: Typical 3–5 years when operated in the temperature range -20° to 40°C (-4°F to 104°F) and positioned toward the sun (see Deployment and Mounting), operation outside this range will reduce the battery service life
With lithium batteries: 1 year, typical use

Memory

16 MB

Dimensions

Cable length: 5 m (16.4 ft)
Mote: 16.2 x 8.59 x 4.14 cm (6.38 x 3.38 x 1.63 inches)

Weight

Mote: 223 g (7.87 oz)

Materials

Sensor: Weatherproof
Mote: PCPBT, silicone rubber seal

Environmental Rating

Mote: IP67, NEMA 6
