Anturien käyttö on lisääntynyt nopeasti teollisuudessa, kun niillä seurataan laitteiston kuntoa ennakoivan huollon ideassa. Tähän asti anturidatasta on pitänyt suodattaa häiritsevä kohina laitteen mikro-ohjaimessa tai prosessorissa. ROHM-ryhmään kuuluvan Kionixin uudet kiihtyyvyysanturit suodattavat kohinan pois jo anturissa.

Kiihtyvyysanturit KX132-1211 ja KX134-1211 ovat ROHM:n mukaan ihanteellisia erittäin tarkkoihin, pienitehoisiin liiketunnistussovelluksiin teollisuuslaitteissa ja kuluttajien puettavilla markkinoilla.

KX134-1211 on 3-akselinen kiihtyvyysanturi, joka on optimoitu koneen tilan seurantaan. ADP-tekniikka (Advanced Data Path) mahdollistaa kohinan suodatuksen ja anturisignaalien prosessoinnin kiihtyvyysanturilla. Tähän asti tämä on tehty mikro-ohjaimella, joten ADP pienentää ohjaimen kuormitusta ja virrankulutusta yhdessä parantuneen sovelluksen suorituskyvyn kanssa.

ADP on Kionixin kehittämä uusi toiminto, joka korvaa perinteisten mikro-ohjainten suodatustoiminnot. Erityisesti anturiin sisäänrakennetut useat muokattavat taajuussuodattimet poistavat tarpeettomat kohinasignaalit ja poimimalla käyttöön vain tarvittavat signaalit. Jokainen suodin voidaan kytkeä päälle ja pois päältä.

Teollisuusvaatimusten täyttämiseksi anturin toimintataajuus on nostettu 8500 hertsiin ja kiihtyvyyden havaitsemisalueet ± 64 g:een samalla, kun ne tukevat käyttölämpötiloja jopa 105 asteeseen.

Anturi itse kuluttaa alle puolet virrasta (0,67µA pienitehoisessa tilassa) verrattuna tavanomaisiin tuotteisiin. Lisäominaisuuksia ovat Wake Up- ja Black to Sleep -toiminnot, jotka osaltaan alentavat tehonkulutusta. Tämä mahdollistaa anturikäytön paristokäyttöisissä puettavissa laitteissa.

KX132-1211 -anturi aistii kiihtyvyyksiä alueella ± 2 g - ± 16 g, kun taas tehokkaampi KX134-1211 yltää ± 8 g:stä aina ± 64 g:een.
