A meteorologicalparameter and atmospheric turbulence measurement system was described in this paper. A/Dconversion was done by VFC (Voltage Frequency Changer). The system has been implemented ata 27 m tower in Gaomeigu Yunnan Astronomical Observatory,that includes three levelsfast-response temperature sensors and two slow-response temperature sensors,a humiditysensor,a pressure sensor,a propeller-vane anemometer,Computer selects input channelsand pulse signal is counted by 8253 counter,so the system cost is low and the measuringprecision of long distance sampling signal can be ensured.
