In this paper, a new type of sensor is designed by way of make full use of the AT89C2051. The sensor has a module of collecting measuring data and long-distance trans mission, and the module consists of serial A/D converter whose differential ratio is 1/2[12] and half-duplex transceiver whose name is MAX485E. The converter's name is TLC2543. the in telligent flow sensor possesses function of long-distance communication with PC interface. The results of the experiment show that the project can be provided with the characteristic of low power, small buldk, very high sampling precision, good dependability and handy interface as well.
