Abstract：The temperature and humidity sensors of HMP45D and HMP155 are mainly used in Beijing regional automatic meteorological station.In order to analyze the observation consistency of the two types of sensors,two sensors of each type are selected for comparative observation at Beijing meteorological observation.The results show that the two kinds of sensors are well consistent with the temperature and humidity observations.There is little difference in temperature measurement performance between the two sensors.The stable performance of HMP155 humidity measurement is better than HMP45D .
