Scarlet WL-21 system measures and displays current/average/maximum wind speed, wind direction, temperature, wind chill, Beaufort scale, atmospheric pressure, and historic data graphic in high accuracy with multiple measurement units. Users are able to set wind speed threshold and receive instant alarm notification when wind speed exceeds the set threshold.
WL-21 measures both wind speed and direction. The sensor has a wind cup on top to measure wind speed and a metal wind direction sensor on the bottom. The sensor is water-proof and dust-tight. It sends real-time measured data to the receiver. All Scarlet’ wind sensor has undergone a strict quality control to ensure accurate measurement.
