基于单片机的数据采集系统的设计

he system used At89C51 monolithic integrated circuit to design a section 8 group data acquisition system, this system might realize A/D to transform, the data processing, D/A transforms, the serial port communication, the data display and reports to the police and so on many kinds of functions.Only must join corresponding sensors and so on temperature, humidity and pressure, then realizes the corresponding multi-channel data acquisition monitor function, but widely applies in each industry domain.
