But along with the time progress, industrial site requires the acquisition and analysis of the data more and more by manpower, has been unable to meet the demand of industrial control, in this context, sensor data acquisition system will emerge as the times require. In recent years, sensor data acquisition and its application technology has attracted more and more attention, sensor data acquisition system has been developing rapidly in chemical production, mining, scientific research, disaster prevention, medical, defense and other fields have a wide range of applications. The design of sensor data acquisition system consists of pressure sensor,AD7705, STC89C52RC and LCD1286. Pressure sensor subjected to pressure, the pressure signal is converted into a low analog voltage signal, then the analog signal after amplification and filtering, and then use the AD7705converts the analog signal to digital signal, and then transmits to the STC89C52RC microcontroller, The microcontroller receive the data to analysis processing, sending the data to the LCD12864. This paper mainly to the completion of sensor data acquisition system in the software part of the design and implementation, including the main function module, data sampling module, keyboard module and display module.
