Mu ma sensing opangira ma photoelectric, omwe amadziwikanso kuti otsutsana, ma transmitter ndi emitter ali m'nyumba zosiyana.Kuwala kochokera ku chotumizira kumalunjika mwachindunji kwa wolandila.Pamene chinthu chikuswa kuwala pakati pa emitter ndi wolandira, zotsatira za wolandira zimasintha.
Kupyolera muzitsulo ndiye njira yabwino kwambiri yomverera yomwe imapangitsa kuti munthu azimva zazitali kwambiri komanso kupindula kwambiri.Kupindula kwakukuluku kumathandizira masensa odutsa-beam kuti agwiritsidwe ntchito modalirika m'malo a chifunga, fumbi komanso auve.
