This product is discontinued.
 

Other Products in this Series

Overview

HOBOnode sensors monitor temperature and soil moisture conditions and wirelessly transmit the data back to your computer.


 

Highlighted Features

  • Fast, easy deployment - sensor's compact size, integrated solar-rechargeable battery makes deployment a snap.
  • .0 to 100% soil moisture range
  • Software provides real-time graphs and alarms to cell phones or local PC; data can be exported for use in other programs.
  • 150 to 300 m (500 to 1000 ft) range with clear line-of-sight. Repeaters are available to extend range.
  • Research-grade reliability and accuracy
  • Complete system requires: Receiver, Sensor, HOBOnode Viewer software. A Repeater is required for greater distances.(sold separately)
  • Includes bracket for convenient mounting on pole or stake

The country of origin for this product is the United States. To see the full specifications for this product, please see our product manual found under the documentation tab if available.

  • Measurement Range:0 to 100% volumetric water content (m^3/m^3)
  • Accuracy - 3.1% (m^3/m^3)
  • Resolution - 0.07% (m^3/m^3)
  • Sample rate -1 reading per minute
  • Battery life - 1 yr typical w/o charging; 3 yrs typical w/ solar charging
  • Size -16.5cm x 5cm; 3.7m cable to sensor (6.5" x 2"; 12' cable)
  • Memory - None in HOBOnodes; requires HOBOnode Viewer to be running for data storage.
  • Transmission range - 150 to 300 m (500 to 1000 ft) range with clear line-of-sight. Any obstructions such as vegetation or walls will reduce range significantly.
  • Wireless Data Standard - IEEE 802.15.4, 2.4 GHz ISM band (license free worldwide) - Click here for local RF Regulation Compliance
  • Operating Range -20° to 50°C (-4° to 122°F) - with optional Lithium Batteries: -40° to 50°C (-40° to 122°F) - Use optional Lithium Batteries in low-temerature and high-temperature applications.
  • Environmental rating - HOBOnodes and Receiver: NEMA 6P, IP68; Repeater: NEMA 4X
  • Setup/Installation:
    • recommend 8' x 1-1/4", schedule 40 PVC pipe for mounting (purchase through local building supply store)
    • for windy locations we also recommend our Guy Wire Kit (M-GWK) and ½" Stake Kit (M-SKA)
    • note that the HOBOnodes should not be mounted on or near metal surfaces.

RS3-B

Use the RS3-B Solar Radiation Shield with HOBO external sensors for improved temperature measurement accuracy in locations exposed to sunlight. The small size and unobstructed airflow of this shield provides a faster response to changing conditions than larger radiation shields.

The RS3-B Solar Radiation Shield works with most of Onset’s external temperature and temperature/relative humidity sensors, including those for our award-winning HOBO Weather Station products.

For customers looking for a radiation shield large enough to mount a HOBO data logger inside it, Onset also offers two other models of solar radiation shields; the RS1 and the pre-assembled M-RSA

S-SMC-M005

This affordably priced soil water content sensor offers a two-tine design for easy installation. In addition, the EC-5 is a smart sensor, which allows users to launch monitoring systems quickly, easily, and affordably. Since HOBO data loggers recognize this sensor, no complicated programming or setup is required. The EC-5 integrates with the field-proven ECH2O™ Sensor and a 12-bit A/D; and provides ±3% accuracy in typical soil conditions, and ±2% accuracy with soil-specific calibration. Readings are provided directly in volumetric water content. This sensor is designed to maintain low sensitivity to salinity and textural effects.
