摘要
国家和地方相继出台了控烟条例,为了辅助监控与警示,基于GP2Y1010AU灰尘传感器,设计了香烟烟雾探测与语音警示电路,当探测到一定浓度的香烟烟雾时,进行语音警示并LED警示灯闪烁提醒,香烟烟雾报警阈值可在0~500μg/m^3范围内改变,以调节系统的灵敏度,达到了公共场合禁止吸烟警示的效果,以MQ-2烟雾传感器探测燃烧烟雾,具有火灾报警作用。
National and local successively introduced tobacco-control regulation, in order to assist monitoring and warning, based on GP2Y1010AU dust sensor, design of the smoke detection and voice alarm circuit, when detected a certain concentration of cigarette smoke, voice alarm and LED warning lights flashing warning, Cigarette smoke alarm threshold can change within 0-500 μg/m^3 range, to adjust the sensitivity of the system, to achieve the effect of smoking is forbidden in public places the alert, MQ-2 smoke sensor detection burning smoke, a fire alarm function.
