基于无线通信的燃气报警器的设计

Design of combustible gas alarm based on wireless communication

针对家居燃气泄漏监控及报警问题,基于STC89C52RC单片机及SIM900A模块设计了一种报警器。该报警器可监控燃气的泄漏情况,同时利用AT指令将报警提醒信息发送到指定手机号码。使用结果表明,在燃气泄漏时该报警器能够有效地运行,达到了预期的设计目标。

For household gas leak monitoring and alarm issues, this paper designs an alarm based on STC89C52RC microcontroller and SIM900A module. Once the alarm monitors the gas leaks, it will using AT commands to send a alarm message to some specified phone number. In practical use, the alarm can effectively monitor the gas leak and achieve the desired goals.
