摘要
由于自然界里的所有物体全部都在或多或少地辐射着红外线,热释电红外报警器就是利用热释电红外传感器的原理,采用多普勒技术,以微波遥测感受移动人体所发出的红外线,并将其转换成电信号输出,从而达到报警及感应开关的作用.
Asall objects all in more or less are completely radiated by infrared, the pyroelectric infrared alarm apparatus are used the principle of the pyroelectric infrared sensor , using the Doppler technology, sending out infrared to feel migration human body by the microwave telemetering, and transforming it the electrical signal to output, thus achieved the function of reports to the police and induces the switch.
