Description
Overview
GAOTech Speed Sensor Instant Wind Speed Alarm WR-3 Plus displays the live wind speed value in selectable measurement units (m/s, knots, MPH, km/hr) Users can set a wind speed warning limit on based on local operation safety standards. An audible and visual alarm will be trigger when the limit has beenreached. Each sensor has a unique wireless address that can connect to several displays to notify multiple stakeholders on-site. WR-3 Plus capture and storage wind speed, temperature, air pressure measurements. 64MB built-in memory and outstanding battery life supports up to 1 year of continuous data recording. (based on 10s logging interval, adjustable: 2s, 5s, 10s, 1min, 5 mins, 10 mins, 60 mins) The recorded data can be easily export in Excel format further analysis.
