Description
Overview
GAOTek ultrasonic air quality tester is simultaneously used to measure the atmospheric temperature, atmospheric humidity, wind speed, wind direction, air pressure and precipitation. TTemperature, humidity , and air pressure sensors is placed within the radiation shield. Wind speed and direction of ultrasonic principle.24G radar detection on rainfall, which can quickly detect rainfall and rainfall intensity. Internal GPS global positioning module and electronic compass can be mounted to the system to give a good indication of latitude and longitude and relative speed, which can calculate the real and virtual wind speed and direction, and is especially suitable for installation on motion vectors, such as special vehicles or vessels, etc.
