    Get accurate soil moisture readings in minutes with the HOBOnet Wireless Sensor Network

    Integrates the field-proven ECH2O™ EC5 Sensor and provides readings directly in volumetric water content. This 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 HOBO RX3000 or the HOBO MicroRX 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 software platform.

    This sensor measures soil moisture and is designed to work with the HOBOnet (HOBO® RX) Wireless Sensor Network in which data is transmitted wirelessly from the sensor mote across the network to the station and then uploaded to HOBOlink® web-based software. With HOBOlink, you can monitor sensor readings, view graphs, set up alarms, download data, and more.


    Features

    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 or 336 data channels per HOBO RX station
    • 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


    Important Information

    A complete system requires at least one HOBO RX3000 Remote Monitoring Station, a HOBOnet Wireless Manager, and a HOBOnet Wireless Sensor OR one HOBO MicroRX Station (which has an integrated HOBOnet Wireless Manager) and a HOBOnet Wireless Sensor. HOBOnet Wireless Repeaters (RXW-RPTR-xxx or RXW-RPTR-B-xxx) can be added to extend the range.

    Sensor Frequency 70 MHz
    METER ECH2O Probe Part
    No.    		 EC-5
    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 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

    Up to 50 wireless sensors or 336 data channels per one HOBO RX station
    Logging Rate 1 minute to 18 hours
    Number of Data Channels 2
    Battery Type / Power Source Two AA 1.2V 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
