ThePIR sensor yozungulira yozungulira led panel kuwalaamatha kuzindikira zochitika zozungulira anthu kudzera mu sensa ya thupi la munthu. Ikazindikira kuti pali munthu amene akudutsa, nyaliyo imangoyaka kuti iwunikire. Ngati palibe amene akudutsa, nyaliyo imazima yokha. Potero kukwaniritsa mphamvu zopulumutsa kwenikweni.

Sensor round lead panel ili ndi cholumikizira mthupi chamunthu chomwe chimatha kuzindikira zochitika za thupi la munthu ndikuzindikira kuyatsa kwanzeru. Zimazimitsa zokha pamene thupi la munthu silikugwira ntchito, zimapulumutsa mphamvu. Otetezeka komanso osavuta: Kupyolera mu kuyatsa kwa induction, malo owunikira otetezeka komanso odalirika amaperekedwa, ndipo amawunikira thupi la munthu likayandikira, kuthetsa vuto la ma switch pamanja. Malinga ndi zosowa za zochitika zosiyanasiyana, kukhudzikako kumatha kusinthidwa kuti zigwirizane ndi kumverera kwa mtunda wosiyana komanso kuthamanga kwa kuyenda.

Mtundu uwu wa PIR sensor kuzungulira denga lotsogolera kuwala ungagwiritsidwe ntchito kwambiri m'malo ogulitsira, maofesi, mahotela, ndi maholo owonetserako kuti apulumutse mphamvu, minda yakunja, nyumba ndi koloko etc.

Mwachidule, aPIR imamva kuwala kozunguliraali ndi ntchito yozindikira thupi la munthu ndipo amatha kusintha kuyatsa molingana ndi zochita za thupi la munthu kuti akwaniritse kupulumutsa mphamvu, kumasuka komanso chitetezo. Zoyenera kuwunikira pazofunikira zosiyanasiyana monga nyumba, malo opezeka anthu ambiri, malo ogulitsa ndi minda yakunja.
