| - | PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. | + | PIR andurid tuvastavad liikumist infrapunakiirguse abil, mis on inimeste keha soojuskiirgus. Anduril on kaks pooljuhtivat materjali, mis on erineva elektrilaenguga. Liikumise korral muutuvad need materjalid erinevalt soojenenud, põhjustades elektrilise signaali, mida saab tõlgendada liikumise indikaatorina. |
