Design of Embedded Indoor Multiple Dangerous Gas Detection Alarm System

Abstract:

This paper describes a embedded system,using ARM processor LPC2148 as the core of hardware,and using MQ series gas sensor as the detection component,and using ENC28J60 as the network communication interface,and using uc / OS-II real-time operating system as software platform for the real-time remote monitoring of density of harmful gases indoor.In this system,voltage signals from MQ sensor will be processed by the ARM micro-controller and be displayed in the LCD.Then they will be compared with the set voltage value.If they are greater than the set value,sound and light alarm will be touched off,and data will be transfered to the network through the ARM ENC28J6 network interface.Above all,the system is able to achieve accurate detection, alarm and remote monitoring indoor dangerous gases.
