Chowunikira tsitsi ndi chida chofunikira kwambiri mumakampani opanga nsalu, chomwe chimagwiritsidwa ntchito kuzindikira tsitsi lililonse lotayirira lomwe lili mu ulusi pamene likuyenda mofulumira kwambiri. Chipangizochi chimadziwikanso kuti chowunikira tsitsi ndipo ndi chida chofunikira kwambiri chomwe chimathandizira makina opindika. Ntchito yake yayikulu ndikuyimitsa makina opindika nthawi yomweyo ulusi uliwonse ukapezeka.

Chowunikira tsitsi chili ndi zigawo ziwiri zofunika: bokosi lowongolera lamagetsi ndi bulaketi ya probe. Chowunikira cha infrared chimayikidwa pa bulaketi, ndipo mchenga umayenda mofulumira kwambiri pafupi ndi pamwamba pa bulaketi. Chowunikiracho chimapangidwa kuti chizindikire ubweya, ndipo chikachita izi, chimatumiza chizindikiro ku bokosi lowongolera lamagetsi. Dongosolo lamkati la microcomputer limasanthula mawonekedwe a ubweya, ndipo ngati likukwaniritsa muyezo womwe wogwiritsa ntchito adatchula, chizindikiro chotulutsa chimapangitsa kuti makina opotoza asiye kugwira ntchito.

Chowunikira tsitsi chimagwira ntchito yofunika kwambiri poonetsetsa kuti ulusi womwe ukupangidwa ndi wabwino. Popanda izi, tsitsi lotayirira mu ulusi lingayambitse mavuto osiyanasiyana monga kusweka kwa ulusi, zolakwika za nsalu, komanso kusakhutira kwa makasitomala. Chifukwa chake, ndikofunikira kukhala ndi chowunikira tsitsi chodalirika kuti muchepetse mavutowa ndikusunga mtundu wa chinthu chomaliza.

Pomaliza, chida chowunikira tsitsi ndi chida chofunikira kwambiri mumakampani opanga nsalu, chomwe chimathandiza kuonetsetsa kuti ulusi wopangidwa ndi wapamwamba kwambiri. Pokhala ndi luso lozindikira ndikuyimitsa makina opindika mwachangu, chipangizochi chingachepetse kwambiri kuoneka kwa zolakwika za nsalu ndi madandaulo a makasitomala.
