一种基于SIM900A的煤气泄漏报警器的设计

本文基于51单片机及SIM900A模块设计了一种煤气报警装置,该报警器能够实时监控环境中煤气的泄漏情况,当传感器检测值高于设定值后迅速发出声光报警,同时向指定用户手机发送报警提醒信息。实验结果表明,在煤气发生泄漏时该报警器能够可靠运行,有效地防止了因煤气泄漏导致的中毒和爆炸等安全事故的发生。

Design of a gas leak alarm based on SIM900A

This paper designs a gas alarm device based on 51 single-chip microcomputer and SIM900A module,the alarm can monitor the gas leakage in the environment in real time,when the sensor detection value is higher than the set value,it will quickly sound and light alarm,at the same time,send an alarm reminder to the designated user’s mobile.The experimental results show that the alarm can operate reliably when the gas leaks,effectively prevent the occurrence of safety accidents such as poisoning and explosion caused by gas leakage.
