         <title>Hva er en PIR-Detektor?</title>

         <description><![CDATA[<div>PIR (Passive Infrared) Detektor detekterer <strong>infrarød stråling</strong>. Den har et <strong>pyroelement</strong>, med en <strong>optisk linse</strong> foran for å utvide synsfeltet til detektoren. <br><br>Moderne PIR-Detektorer bruker FSP signalbehandling for å skille mennesker fra andre feilkilder som kan forårsake en falsk alarm.<br>Grunnen til at detektoren heter "passiv" er fordi PIR-D ikke bruker energi for å detektere, den kun generer energi ved observasjon av IR-signaler</div>]]></description>

         <description><![CDATA[<div>PIR-Detektorer brukes i innbruddsalarmanlegg og i viltkameraer.&nbsp;Det kan også brukes til å slå av og på lyset i klasserommet automatisk, eller kanskje du har et slikt lys i garasjen eller utenfor huset?</div>]]></description>
