Abstract:
The pulse oxygen saturation monitoringmodule based on a single chip microcomputer is introduced in this paper. With thismodule, oxygen saturation can be monitored timely, non2invasively and continuously. Themodule a dop ts transmission type oxygen saturation sensor. The light signal electro2circuit and the configuration chart of the pulse oxygen saturation monitoringmodule are p resented in this paper. The module has the function of eliminating nature light and electrical noise in hardware and software, so it can detect oxygen saturation and pulse accurately. In addition, we use single chip microcomputer C8051 asmain controller and p rocessor, which ismade by Cignal compa ny and is of 12bitA /D and 10bitD /A, so the module do not need additionalA /D orD /A. Thus not only the opera tion speed is increased, but also the cost is reduced and the design of the electrical circuit is simp le. Experiment shows that thismodule has characteristics of simp le construction, good stability, anti2interference ability and high ac curacy.
