Abstract:
Several experiments were made by means of the micro multirotor UAV (Unmanned Aerial Vehicle) carrying device to conduct air temperature and relative humidity observation. The results show: (1) the observing data transmission stability is better when using the 433MHZ wireless transmission; (2) the temperature and relative humidity sensors pass the metrological verification; (3) the air temperature and relative humidity consistency between this device and the shelter in the National Automatic Weather Station is better; (4) during the hovering, the observation error is less and the correlation is good between two devices; (5) when using the device and a radiosonde at the same time, the mean absolute error of is 084 ℃ for air temperature and 4% for relative humidity, and there appeared smallamplitude changes in temperature and relative humidity, which can attribute to the response time, ventilation and radiation protector, flying speed, etc.
