* The Parallax PIR Sensor is an easy to use digital infrared motion sensor module.
* (http://www.parallax.com/detail.asp?product_id=555-28027)
*
* The sensor's output pin goes to HIGH if motion is present.
* However, even if motion is present it goes to LOW from time to time,
* which might give the impression no motion is present.
* This program deals with this issue by ignoring LOW-phases shorter than a given time,
* assuming continuous motion is present during these phases.

Arduino eskizida siz sensorning o'z-o'zini sinab ko'rishini va keyin harakatni kuzatish rejimiga o'tishini ko'rishingiz mumkin. Harakat aniqlanganda, LED yonadi. Serial Monitor yordamida harakat qancha davom etganini kuzatishingiz mumkin.
Ushbu loyiha xavfsizlik signalizatsiyalarida, chiroqlarni yoqishda, robototexnikada va hokazolarda harakatni aniqlash uchun asos sifatida ishlatilishi mumkin.
