Abstract: The whole air conditioner control system scheme is drawn, and then the hardware and software of intelligent instrument is designed. It adopts module design method, including signal sampling circuit, I/O interface circuit, LED display and the keyboard input circuit, the communication interface module, the clock and the “Watch Dog” module design. At last, the main structure of the software design is introduced in summary.
