Kusintha kwa sensa ya ONPOW91 ndi ONPOW92 IR ndi kamangidwe katsopano kamene sikamalumikizana ndi anthu.Kugwiritsiridwa ntchito kwa chinthu chomwe chiyenera kuzindikiridwa pa kusintha kwa kuwala kwa infrared kuwala ndi kusinkhasinkha, kungakhale ndi chizindikiro cha LED, makamaka choyenera malo amdima, kuyankhidwa kwapadera kwa kapangidwe kameneko kungapangitse wogwiritsa ntchito bwino.
Pamene mliri ukufalikira, timafufuza mwachangu ndikukulitsa.Kusinthaku kwapangidwa kuti kugwiritsidwe ntchito popewera miliri yasayansi, kuteteza chilengedwe, komanso kudzipatula kwapang'onopang'ono kwa majeremusi ndi ma virus omwe amadza chifukwa chokhudzana ndi thupi.
Amagwiritsidwa ntchito kwambiri m'makina, chitetezo, zamankhwala, zamagalimoto, kuzindikira utsi ndi mafakitale opanga makina.Sizingokhala ndi mawonekedwe a switch switch ndi micro switch, komanso imakhala ndi magwiridwe antchito, magwiridwe antchito okhazikika azinthu, ma frequency oyankha mwachangu, odana ndi kusokoneza, osalowa madzi, osagwedezeka, osawononga dzimbiri komanso okhazikika.
