摘要
被动型热释电红外报警器把红外线的隐蔽性很好地应用于报警系统中。利用热释电红外传感器作为探头,进行非接触式远距离检测,将感测到的红外信息转换成电压信号,经过单片机处理,完成数码显示和语音报警功能,从而实现了防盗报警功能,达到了安全防护的目的。
The muhi -circuitry heat- releasing infrared sense- alarming device is a subject including software and hardware systems which combines the technology of transducer, singlechip and microelectronics. This kind of alarming device makes use of heat - releasing infrared transducer, which can discem the special infrared rays of the human body and transform them to electrical signals, then send the signals to single chip.
