车载有毒气体CO痕量检测报警系统研究

Abstract

Abstract:

Real-time CO concentration detection alarm system is based on single chip microcomputer AT89S52.A sensitive carbon monoxide TGS2600-B00 sensor is used for detecting CO samples in the air.The sensor resistance changes reflect the change of the concentration.It treats the data are converted by AD converter ADC0809 before they are processed by single-chip computer.The current CO concentration is showed on the LED in real time and an alarm is activated if it exceeds 30×10^-6.This system has the advantages of high sensitivity,simple structure,small size and easy installation.It can find applications in avoiding traffic accidents and monitoring physical and mental health.

Key words: CO gas sensor;poisonous gas;detection of trace warning system;single chip microcomputer
