Description
Overview
GAOTek dust sensors air quality tester simultaneously measures the atmospheric temperature, atmospheric humidity, wind speed, wind direction, air pressure and precipitation. Temperature, humidity and air pressure sensor are placed within the radiation shield. Wind speed and direction of ultrasonic principle. 24 G 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 vector, such as special vehicles or vessels, etc.
