Na'urar firikwensin na'ura ce da ke samar da alamu fitarwa don manufar sanin wani abu na zahiri.
A cin mafi faɗin ma'anar, firikwensin shine na'ura, module, inji, ko tsarin ƙasa wanda ke gano abubuwan da suka faru ko canje-canje a cikin muhallinsa kuma yana aika bayanan zuwa wasu na'urorin lantarki, akai-akai na sarrafa kwamfuta.

Ana amfani da na'urori masu auna firikwensin kamar potentiometers da masu iya ji da ƙarfi har yanzu. Aikace-aikacen su sun haɗa da masana'anta da injina, jiragen sama da sararin samaniya, motoci, magunguna, robotics da sauran fannonin rayuwarmu ta yau da kullun. Akwai faffadan sauran na'urori masu auna firikwensin da ke auna sinadarai da kaddarorin jiki na kayan, gami da firikwensin gani don auna ma'aunin refractive, firikwensin jijjiga don ma'aunin dankowar ruwa, da na'urori masu auna sinadarai na lantarki don lura da pH na ruwaye.
Hankalin firikwensin yana nuna yawan canjin kayan aikin sa lokacin da adadin shigarwar da yake auna ya canza. Misali, idan mercury a cikin ma'aunin zafi da sanyio ya motsa 1 cm lokacin da zafin jiki ya canza da 1 °C, hankalinsa shine 1 cm/°C (shine madaidaicin gangaren dy/dx yana ɗaukan siffa ta layi).
