Resurssirajoitteisiin laitteisiin ja langattomiin viestintätekniikoihin perustuvat ratkaisut voivat muodostaa autonomisia sensoriverkkoja, joka mahdollistaa toimintaympäristön seurannan ja tietojenkäsittelyn paikallisesti. Resurssirajoitteiset laitteet, kuten sensorit ja IoT-laitteet, voivat kommunikoida keskenään ja olla vuorovaikutuksessa ulkopuolisten palveluiden kanssa Internetin välityksellä. Fyysisestä maailmasta kerättyjen tietojen perusteella järjestelmän laitteet – joko itsenäisesti tai pilvituen avulla – käsittelevät tietoja ja vuorovaikuttavat ympäristönsä kanssa.
Yksikön osaaminen perustuu usean vuoden kokemukseen yritysyhteistyöstä sulautettujen järjestelmien ja langattomien teknologioiden parissa, ja sillä on oma kehitysalusta IoT-sovellusten toteuttamiseen.

Informaatioteknologian yksikkö on toteuttanut useita langattoman sensoriverkon noodeja vuosien varrella. Olemme käyttäneet pääasiassa Atmelin mikrokontrollereita ja radioita, jotka ovat IEEE802.15.4 standardin mukaisia.
CinetNodeV5 (2017)
Uusin alusta jota käytämme projekteissa on omaa suunnittelua laitteiston ja ohjelmiston osalta.
Atmega128L+ Chipcon CC2420
CinetNodeV2 (2009)
Jennic JN5139 (integrated 2.4GHz radio)
CinetNodeV3 (2013)
Tästä versiosta on kahta eri tyyppiä 2.4GHz ja 868MHz radiolla. Molemmat perustuivat Atmel Zigbit moduuleihin.
