Description
Overview
GAOTek wind direction Sensor is composed of several sensors to measure wind speed & direction based on ultrasonic sound wave travel time difference in air, it has optional temperature, humidity and pressure sensors. It’s a versatile handheld micro meteorological station, which has a screen to display real-time detection data. It has advantages of light weight (ABS plastic shell), robust features, no moving parts, free of maintenance and site calibration, it can simultaneously output wind speed and direction, temperature, humidity, atmospheric pressure. Specially designed handle, convenient for users’ operation with single hand, weight only 1.87 lb (0.85 kg). User can acquire real-time data through APP on phone connected to SEMI4000 by Bluetooth module, it’s especially suitable for fled inspection.
Features
