摘要
随着时代的进步,人们对环境的安全性提出更高的要求,于是设计一个行之有效的安全警报器有很大的必要,而这里所设计的安全报警器则采用了传感元件——热释电红外传感器。这种热释电红外传感器能以非接触形式检测出人体辐射的红外线,并将其转变为电压信号。热释电红外传感器既可用于安全报警装置,也可以用于自动控制、接近开关、遥测等领域。它是结合单片机、电子基础、传感器为一体的新技术。
With the progress of the times, the higher requirements for safe environment is put forward, so it isecessary to design an effective security alarm. The security alarm here designed adopts the electric infrared sensor, which can detect the infrared radiation to the human body with a non - contact method, and convert it into a voltage signal. This sensor is not only used in security alarm device, but also can be used in the field of auto control, proximity switch, remote surveying and so on. It is a new technology combining the technology of SCM, electronic elements and sensor as the whole.
