A\u010dkoli vypadaj\u00ed identicky, senzory p\u0159\u00edtomnosti (occupancy) a nep\u0159\u00edtomnosti (vacancy) funguj\u00ed na odli\u0161n\u00fdch principech. Senzor p\u0159\u00edtomnosti je zcela autonomn\u00ed a automatizuje jak \u201ezapnut\u00ed\u201c, \u0442\u0430\u043a i \u201evypnut\u00ed\u201c.
