What is PIR sensor? • PIR Sensor or Passive infrared sensor allows for sense motion.They are almost always used to detect whether a human has moved in or out of the sensors range. • PIRs are basically made of a pyroelectric sensor which can detect levels of infrared radiation.Every object emits heat energy in the form of radiation.For a human, heat is radiated as infrared.This radiation is not visible to naked eye.But this radiation can be detected by the PIR sensor. • Watch more: • what is buzzer? • https://goo.gl/LHKWdx • • What is a Thermistor? • https://goo.gl/yqP8LJ • what is rpm meaning | what is rpm of dc motor • https://goo.gl/zSmpPR • what is a piezoelectric sensor? • https://goo.gl/mExQb4 • What is mAh in Battery • https://goo.gl/97bN56 • • what is light dependent resistance (LDR) • https://goo.gl/yZhRq3 • what is motor shield | why motor shield ?
