The system that measures air temperature,pressure,relative humidity in low altitude atmosphere based on atmosphere refractivity is presented.The system includes a data collection board and portable receiving terminals to realize multipoint data acquisition.The model of component,schematics and software process are introduced.The measuring results are compared with those from automatic weather station,which show that the system meets the precision requirement (temperature:±0.2 ℃,humidity:3 %,air pressure:±0.2 hPa).Being convenient,battery-efficient,reliable and with a high precision,the system can be carried on the ship to forecast evaporation duct.

Key words: atmosphere refractivity;weather data collection;CC2530;sensors
