Uchungechunge lwe-A13 imodyuli ye-sensor ye-ultrasonic eyenzelwe kunye nesakhiwo esibonakalisayo, imodyuli yimodyuli ephezulu, ethembekileyo yokuthengisa-ibakala elisebenzayo eliphuhliswe ngokukodwa kwisisombululo se-trash bin.
I-A20-modyuli isekelwe ekusetyenzisweni kweprobe evaliweyo yokwahlula kwamanzi. Iprobe ye-Ultrasonic ithatha i-anti-water technology design, inciphisa ngokufanelekileyo ingxaki ye-probe condensation, i-IP67 efanelekileyo kwiindawo ezinzima.
