Abstract
This paper describes particularly the design and research of an ultra-low-power data acquisition system. It uses LPC2132 as micro controller along with LCD display module and the data communication module, and uses the embedded operating system μC / OS-II to manage the communication and switching between tasks. This system realizes the function of real-time acquisition and display in analog signal and digital signal, and if necessary, the data will be sent to the host computer. The system runs stable, low power consumption and easy to carry.
