Ko te kōwae A15 he kōwae e whakamahi ana i te hangarau ultrasonic sensing mo te ine tawhiti. Ka tangohia e te kōwae te pūtukatuka mahi teitei, nga waahanga kounga teitei me te hoahoa tirotiro wai. He pūmau, he pono te pūoko, he roa te oranga. He tino pai ki te ahua kino o te mahi. Kei roto i te kōwae he hanga-i roto i te tino-nui-nui-a-te-rangi algorithm me te kaupapa whakahaere mana, me te tino tika me te iti o te whakapau hiko.
