-Thermistor

Thermistor shine na'urar gano zafin jiki wanda juriya ce ta yanayin zafinsa.Akwai nau'ikan thermistors iri biyu: PTC (Positive Temperature Coefficient) da NTC (Negative Temperature Coefficient).Juriya na thermistor PTC yana ƙaruwa da zafin jiki.Sabanin haka, juriya na thermistor na NTC yana raguwa tare da ƙara yawan zafin jiki, kuma irin wannan nau'in thermistor yana kama da mafi yawan amfani da thermistor.

-Thermocouple

Ana amfani da thermocouples sau da yawa don auna yanayin zafi mafi girma da kuma girman zafin jiki.Thermocouples suna aiki akan ƙa'idar cewa duk wani jagorar da aka yiwa ma'aunin zafi na zafi yana samar da ƙaramin ƙarfin lantarki, al'amarin da aka sani da tasirin Seebeck.Girman ƙarfin lantarki da aka samar ya dogara da nau'in karfe.Akwai nau'ikan thermocouples da yawa dangane da kayan ƙarfe da aka yi amfani da su.Daga cikin su, haɗin gwal sun zama sananne.Nau'o'in haɗin ƙarfe daban-daban suna samuwa don aikace-aikace daban-daban, kuma masu amfani yawanci zabar su bisa ga yanayin zafin da ake so da azanci.

-Mai gano zafin juriya (RTD)

Masu gano yanayin zafin juriya, kuma aka sani da ma'aunin zafi da sanyio.RTDs sun yi kama da thermistors saboda juriyarsu tana canzawa da zafin jiki.Koyaya, maimakon amfani da kayan musamman waɗanda ke kula da canjin yanayin zafi kamar thermistors, RTDs suna amfani da coils da aka raunata a kusa da ainihin waya da aka yi da yumbu ko gilashi.Wayar RTD abu ne mai tsafta, yawanci platinum, nickel ko jan karfe, kuma wannan abu yana da madaidaicin juriya-zazzabi alakar da ake amfani da ita don tantance zafin da aka auna.　

-Analog thermometer IC

Madadin yin amfani da thermistors da ƙayyadaddun masu tsayayyar ƙima a cikin da'ira mai rarraba wutar lantarki shine a kwaikwayi ƙananan firikwensin zafin wuta.Ya bambanta da thermistors, analog ICs suna ba da wutar lantarki kusan madaidaiciya.

-Digital thermometer IC

Na'urorin zafin jiki na dijital sun fi rikitarwa, amma suna iya zama daidai.Hakanan, suna iya sauƙaƙe ƙirar gabaɗaya saboda canjin analog-zuwa-dijital yana faruwa a cikin ma'aunin zafi da sanyio IC maimakon na'urar daban kamar microcontroller.Hakanan, ana iya daidaita wasu ICs na dijital don girbi makamashi daga layin bayanansu, suna ba da damar haɗin kai ta amfani da wayoyi biyu kawai (watau bayanai/iko da ƙasa).
