Abstract: In this paper, taking STC15W1K24S single chip microcomputer as the core controller, the working principle of PCF8591 is analyzed;with the gas concentration of gas sensor collected by single chip microcomputer as an example, an automatic control system for gas concentration monitoring is designed; and the communication code between single chip microcomputer and PCF8591 is given. The design code has been verified in the actual equipment, and the gas concentration of the gas sensor can be collected correctly.

Keywords: PCF8591; communication; code design; STC15W1K24S single chip microcomputer; sensor
