A remote data acquisition and transmission terminal,which was made up of GPRS module SIM300C and MCU AT89S52 was proposed.This paper introduces the hardware and software design of the system.MCU Was the main controller.With the A/D converter circuit,SIM300C and its peripheral circuit,the system collected the anMog voltage or current signals from the sensors,which were converted to digital data by A/D conversion chips.Then MCU packed the digital data and sent them to SIM300C by serial port.Digital data was sent to remote server through GPRS wireless communication network.The test results indicate,the system is stable and reliable.It can accomplish data transmission timely and efficiently.
