Research of Indoor Carbon Monoxide Monitor and Alarm System Based on Single-Chip Microcomputer
Abstract: This paper presents a carbon monoxide alarm system designed by the combination of AT89C51 single-chip and sencors of electrochemical CO/F1000. The function of the system is to give the concentration of indoor carbon monoxide monitoring and alarming based on the many features of single-chip microcomputer and a high degree of selectivity and accuracy of electrochemical sensors . The principles and use ways of the carbon monoxide gas sensor are introduced. The monitoring circuit which is composed of the sencors,operational amplifiers, microcontroller, and alarm circuit etc can complete monitoring and alarming work of indoor carbon monoxide.
Key words: Single-chip ATC8951; Gas sensor; Carbon monoxide; Alarm
