Reed Switches da Hall Excelors
Ana amfani da maganyacin magnetic a cikin komai daga motoci zuwa CRAPhones. Abin da Magnet ya kamata in yi amfani da maganata ta magnetic? Shin ya kamata in yi amfani da hancin harkar Hall ko kuma Reed Canjin? Ta yaya za a iya daidaita gumnawa? Wane haƙuri ne yakamata in damu? Moreara koyo tare da K & J Walk - ta hanyar tantance hadewar magnet-firikwen.

Mene ne Reed Canjin?

Hannun Main Hill Halls da Reed Canjin. Reed sauyawa yana hannun dama.
Sauyawa na Reed shine canjin lantarki wanda aka yi amfani da filin magnetic. Ya ƙunshi wasu lambobi biyu a kan ƙarfe na ƙarfe a cikin ambulaf na gyaran gidan na Airthight. Lambobin suna buɗe kullun, ba su da lambar lantarki. An yi sauyawa (a rufe) ta hanyar kawo magnet kusa da canjin. Da zarar an cire Magnet, Read na Reed zai koma ainihin matsayin sa.

Menene tasirin mafarkin?
A sakamakon mafaka shine mai canzawa wanda ya bambanta da kayan aikinta don amsawa don canje-canje na magnetic. A wasu hanyoyi, zauren zauren zail na iya aiwatar da irin wannan aikin a matsayin real sauyawa, amma ba tare da sassan motsi ba. Ka yi tunanin shi a matsayin wani abu mai ƙarfi-jihar, mai kyau ga aikace-aikace na dijital.

Wanne ne daga cikin waɗannan na'urori masu kyau biyu daidai ne don aikace-aikacenku ya dogara da abubuwa da yawa. Abubuwan sun haɗa da farashi, maganganun mita, Rukunin mita (sake siyarwa yawanci ba zai iya amfani da 10 khz), ƙyallen sigina da ƙirar alamomi masu alaƙa.

Magnet - Farko Sensor
Mahimmin bambanci tsakanin reed Switches da Halarfin Hall shine ingantacciyar koyarwa da ake buƙata don kunna magnet. Hanyoyin aikin kwalliyar zaunan suna kunnawa lokacin da filin magnetic wanda yake perpendicular ga mai ƙarfi-jihar ana amfani dashi. Mafi yawan sonta na Kudu na Kudu da za a iya fuskantar wurin da aka nuna a kan firikwensin, amma duba takardar dimeti na firikwarka. Idan ka juya magnet da baya ko gefe guda, firikwensin ba zai kunna ba.
