HOBOnet Ultrasonic Wind Speed & Direction Sensor

Ein kabelloser Ultraschall-Windgeschwindigkeits- und -Richtungssensor, der mit HOBOnet arbeitet und sehr niedrige Windgeschwindigkeiten (bis zu 0,4 m/s) messen kann.

Wichtige Informationen

Ein vollständiges System erfordert mindestens einen HOBO RX3000 Fernüberwachungsstation, a HOBOnet Drahtlos-Manager, und eine HOBOnet Drahtloser Sensor, ODER eine HOBO MicroRX-Station (mit integriertem HOBOnet Wireless Manager) und einem HOBOnet Drahtloser Sensor. HOBOnet Funk-Repeater (RXW-RPTR-xxx oder RXW-RPTR-B-xxx) können hinzugefügt werden, um die Reichweite zu erhöhen.

Overview

A wireless ultrasonic wind speed & direction sensor that works with HOBOnet. Compact and rugged, with no moving parts, this ultrasonic sensor can measure very low wind speeds, down to 0.4 m/s (compared to 1.0 m/s for our mechanical sensors). 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.

Specifications

Sensor

	Wind Speed/Gust	Wind Direction
Measurement Range	0 to 41.16 m/s (0 to 92.07 mph)	0 to 359 degrees
Accuracy	±0.8 m/s (1.79 mph) or ±4% of reading, whichever is greater	0.2 to 3 m/s (0.44-6.7 mph): ±4 degrees >3 m/s (6.7 mph): ±2 degrees
Resolution	0.4 m/s (0.89 mph)	1 degree (0 to 359 degrees)
Measurement Definition	Wind speed readings are taken 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 See Measurement Operation.	Unit vector averaging used; vector components for each wind measurement are calculated every three seconds for duration of logging interval (see Measurement Operation)
