PIR(PASSIVE INFRARED)센서
Focusing devices for pyroelectric infrared sensors http:// www.glolab.com Pyroelectric infrared sensors First we will look at a pyroelectric infrared sensor and see how it is made and why a focusing device is necessary. A commonly used pyroelectric infrared sensor has two sensing elements internally connected in a voltage bucking configuration. 초전기(焦그슬릴,초 電전기,전 氣기운,..
