This paper proposes a module of data acquisition and wireless transmission based on the ARM7 embedded system.Firstly,we introduce a data acquisition station system based on LPC2220 chip,and shows the design of a wireless transmission module which is composed of the embedded LPC2220 microprocessor and the chip of nRF905.When it works at 868 MHz,the rate of data transmission is 1 Mbit·s-1.The effective transmission radius can reach 800 meters with good stability by using the high gain antenna.The design has the advantages of high precision,high speed and real-time data acquisition and wireless transmission.
