Sensor ea khatello, e le karolo ea bohlokoa ea ho lemoha indastering ea morao-rao le saense le thekenoloji, e ka fetola lets'oao le lemohuoang la khatello hore e be lets'oao la motlakase kapa mefuta e meng ea tlhahiso ea matšoao. Molao-motheo o sebetsang oa sensor ena o itšetlehile ka liphello tsa 'mele, tse kang liphello tsa piezoresistive, liphello tsa piezoelectric, joalo-joalo, ho e lumella ho lekanya ka nepo le ho bonahatsa liphetoho tsa khatello libakeng tse sa tšoaneng. Tlhahisong ea indasteri, li-sensor tsa khatello li sebelisoa haholo taolong ea mokelikeli, ho lemoha khase, melapo ea tlhahiso e ikemetseng le likarolo tse ling ho netefatsa botsitso le polokeho ea ts'ebetso ea tlhahiso. Ka nako e ts'oanang, ho tsa bongaka, ts'ireletso ea tikoloho, lipalangoang le liindasteri tse ling, li-sensor tsa khatello le tsona li phetha karolo ea bohlokoa, joalo ka ho lekola khatello ea mali, ho bona boleng ba moea, ho lekanya khatello ea lebili la koloi joalo-joalo. Lisebelisoa tsena ha li ntlafatse bokhoni ba mosebetsi feela, empa li boetse li tlisa boiketlo bophelong ba batho.
