This article takes Data Acquisition System as core to launch, describes the general-purpose data acquisition system composed of communication systems, focus on the next-bit machine with PC-wireless communications. . The topics are designed data acquisition system is indoor / outdoor, industrial site and the wiring of the difficult place of Analog sensor, DC voltage monitoring, measuring.The 89S52 microcontroller system as a whole core of the control system, consists of LCD module 1602, EEPROM chip AT24C16, wireless transmission module PTR8000+, A/D converter chip TLC2543, serial communications, composed of data acquisition system. The system uses A/D converter chip TLC2543 to measure analog-type sensors, voltage data acquisition. Then the value of the data return microcontroller and displayed on the LCD module. when the system settings to the data to launch mode, the data sent to the computer through wireless transmission module PTR8000+ , and through a standard RS232 communication interface to collected data to PC, making data stored and management . In addition AT24C16 can be used to stored the data collected by hand. At the same time,the data can be display which was saved by LCD. The subject completed the entire system of hardware and software design, the design is a multi-purpose data acquisition system which applied to an indoor / outdoor, industrial site. Key words: Data acquisition Serial Communication PTR8000+ TLC2543
