HOBOnode Soil Moisture - Wireless Sensor
Discontinued
HOBOnode sensors monitor temperature and soil moisture conditions and wirelessly transmit the data back to your computer.
Easy to deploy soil moisture wireless sensor
Overview
HOBOnode sensors monitor temperature and soil moisture conditions and wirelessly transmit the data back to your computer.
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
Specifications
- 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.
