This article describes a microcontroller-based data acquisition hardware and software design, data acquisition system is the essential link between the analog and digital domains, and its presence has a very important role. The focus of this paper is the data acquisition system, and part of the center of gravity of the system hardware is that the microcontroller. The hardware part is a microcontroller as the core, but also including the A/D conversion module, LCD1602 display module part. The measured voltage of the 8-way through the ADC ADC0809, the analog-to-digital conversion, analog to digital conversion on the data collected, and the converted data through the LCD1602 display to display the results collected, and can be button to view the voltage value of an arbitrary path, the entire system with easy operation, simple circuit, the measurement error is small, etc.. Keywords: microcontroller AT89S52, analog-to-digital converter ADC0809 data acquisition, LCD1602 display
