Canada’s Instrumentation Leader Since 1946.
A wireless sensor that works with HOBOnet to record wind speed, wind gust, and wind direction. 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-based software platform.
In what environment does this sensor operate?
This sensor operates in an outdoor environment.
What measurements does this sensor support?
The RXW-WCF-xxx sensor supports the following measurements: Evapotranspiration and Wind
HOBOnet Field Monitoring System
The NEW HOBOnet Field Monitoring System from Onset provides a cost-effective and scalable solution for web-enabled monitoring of field conditions for applications such as crop management, research, and greenhouse operations.
|Wind Speed/Gust||Wind Direction|
|Measurement Range||0 to 76 m/sec (0 to 170 mph)||0 to 355 degrees|
|Accuracy||±1.1 m/sec (±2 mph) or ±5% of reading,
whichever is greater
|Resolution||0.5 m/sec (1.1 mph)||1.4 degrees (0 to 355 degrees)|
|Starting Threshold||≤1 m/sec (2.2 mph)||1 m/sec (2.2 mph)|
|Turning Radius||108 mm (4.25 in.)||Approximately 135 mm (5.25 in.)|
|Measurement Definition||Cup revolutions are accumulated every three seconds for the
duration of the logging interval
Wind speed: Average speed for the entire logging interval
Gust speed: The highest three-second wind recorded during the logging interval
|Unit vector averaging used; vector components for each wind measurement are calculated every three seconds for duration of logging interval|
|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-WCF-900: 904–924 MHz
RXW-WCF-868: 866.5 MHz
RXW-WCF-922: 916–924 MHz
|Modulation Employed||OQPSK (Offset Quadrature Phase Shift Keying)|
|Data Rate||Up to 250 kbps, non-adjustable|
|Maximum Number of Motes||50 motes per one RX Wireless Sensor Network|
|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|
