XDB403 ikurikirana yubushyuhe bwo hejuru ikwirakwiza ibyuma bya silikoni yatumijwe mu mahanga, ibicuruzwa biturika bituruka mu nganda hamwe n’ubushyuhe bwa bffer, imbonerahamwe yerekana LED, ituze ryinshi hamwe n’umuvuduko ukabije wa piezoresistive sensor hamwe n’umuzunguruko wihariye. Nyuma yo gupima mudasobwa yikora, indishyi zubushyuhe, ikimenyetso cya milivolt ya sensor ihindurwamo voltage isanzwe nibisohoka byerekana ibimenyetso, bishobora guhita bihuzwa na mudasobwa, igikoresho cyo kugenzura, ibikoresho byerekana nibindi, kandi birashobora gukora ibimenyetso birebire byerekanwa. .
