Ma alamu masensanthawi zambiri amagwira ntchito pozindikira kusintha kwa thupi monga kusuntha, kusintha kwa kutentha, phokoso, ndi zina zotero. Sensa ikazindikira kusintha, imatumiza chizindikiro kwa wolamulira, ndipo wolamulirayo adzakonza chizindikirocho motsatira malamulo omwe atchulidwa kale, ndipo pamapeto pake amatha. perekani alamu kudzera m'buzzer, chiwonetsero kapena njira zina.Kuphatikiza pa kuzindikira kusintha kwa thupi, masensa a alamu amagwiranso ntchito pozindikira kusokonezedwa ndi ma siginecha opanda zingwe, mphamvu ya mafunde a electromagnetic, ndi zina.Mwachitsanzo, maginito opanda zitseko a zitseko amazindikira ngati zitseko ndi mazenera atsekedwa pozindikira kusokoneza kwa zizindikiro zopanda zingwe;PIR (pyroelectric) zowunikira zoyenda zimazindikira kusuntha pozindikira ma sign a pyroelectric amunthu.Kuphatikiza apo, sensa ya alamu imathanso kugwiritsa ntchito matekinoloje osiyanasiyana omvera kuti agwire ntchito molingana ndi momwe amagwiritsira ntchito.Mwachitsanzo, alamu yamoto imatha kugwiritsa ntchito zida za utsi;anyumba chitetezo dongosoloamatha kugwiritsa ntchito masensa a infrared, ndi zina zotero.

Mfundo yogwirira ntchito ndi machitidwe a masensa a alamu ndizofunikira kwambiri pachitetezo chawo komanso kudalirika.Chifukwa chake, masensa a ma alarm amayenera kuyesedwa mozama ndikutsimikizira kuti amatha kuzindikira bwino zomwe zafotokozedweratu ndikuyimba alamu.Nthawi yomweyo, masensa a alamu amafunika kukonzedwa pafupipafupi ndikuwunika kuti atsimikizire kuti akugwira ntchito moyenera.Mwachitsanzo, ma sensor a utsi amayenera kutsukidwa nthawi zonse kuti ateteze ma alarm abodza chifukwa cha kuchuluka kwa utsi, ndipo zowunikira za PIR ziyenera kuyesedwa pafupipafupi kuti zitsimikizire kuti zitha kuzindikira bwino kuyenda.Nthawi zambiri, sensor ya alamu ndi chida chofunikira kwambiri chachitetezo chomwe chingatithandize kupeza ndikupewa ziwopsezo zosiyanasiyana zachitetezo pasadakhale.Chifukwa chake, tiyenera kuyisamalira ndikuigwiritsa ntchito moyenera kuti iwonetsetse kuti ikugwira ntchito bwino.
Magawo ogwiritsira ntchito ma alarm sensors ndi otakata kwambiri ndipo akukulirakulira nthawi zonse.Atha kugwiritsidwa ntchito m'makina otetezera kunyumba, kumanga makina opangira makina, makina opangira mafakitale, makina oyendetsera magalimoto, machitidwe azaumoyo, ndi zina zambiri.
M'makina achitetezo apanyumba, masensa a alamu amatha kugwiritsidwa ntchito kuti azindikire ngati zitseko ndi mazenera ali otseguka, kuzindikira zinthu zomwe zikuyenda, ndi zina zotero, kuteteza chitetezo chabanja.
Pomanga makina opangira makina, masensa a alamu angagwiritsidwe ntchito kuyang'anira machitidwe otetezera moto, machitidwe owonetsetsa zachilengedwe, ndi zina zotero kuti ateteze chitetezo cha ogwira ntchito.
M'makina opanga makina opanga ma alamu, masensa a alamu amatha kugwiritsidwa ntchito kuyang'anira mizere yopanga, kuzindikira kulephera kwa makina, ndi zina zambiri, kuti apititse patsogolo kupanga.
M'machitidwe oyendetsera magalimoto, masensa a alamu angagwiritsidwe ntchito kuyang'anira momwe magalimoto alili, kuzindikira ngozi zapamsewu, ndi zina zotero, kuonetsetsa chitetezo cha pamsewu.
M'machitidwe azachipatala, masensa a alamu angagwiritsidwe ntchito kuyang'anira thanzi la odwala, kuzindikira kulephera kwa zida zachipatala, ndi zina zotero kuti odwala akhale ndi thanzi.
Kuphatikiza pa zomwe tazitchula pamwambapa, masensa a alamu atha kugwiritsidwanso ntchito m'magawo ena, monga:
Kuyang'anira Zachilengedwe: Zowunikira ma alarm zitha kugwiritsidwa ntchito kuwunika momwe mpweya ulili, mtundu wamadzi, kuipitsidwa kwa nthaka, ndi zina zambiri.
Chitetezo cha Zinyama: Ma alamu amatha kugwiritsidwa ntchito kuyang'anira mayendedwe a nyama, kuzindikira zochitika za nyama, ndi zina.
Ulimi: Zowunikira ma alarm zitha kugwiritsidwa ntchito kuyang'anira chinyezi chamunda, chinyezi cha nthaka, kutentha kozungulira, ndi zina zambiri.
Chitetezo cha anthu: Ma alamu amatha kugwiritsidwa ntchito kuyang'anira kayendedwe ka anthu, moto, ndi zina zambiri m'malo opezeka anthu ambiri.
Ntchito ndi mitundu yogwiritsira ntchito ma alarm sensors ikukulirakulira nthawi zonse, ndipo idzakhala gawo lofunikira kwambiri pamakina anzeru komanso odzichitira okha.
An alamu sensornthawi zambiri imakhala ndi sensor yokha, unit control, trigger, alarm device, etc.
Sensa yokhayo ndiyo gawo lalikulu la sensor ya alamu, yomwe imayang'anira chilengedwe chozungulira ndikupanga deta.
Chigawo chowongolera ndi malo olamulira a alamu, omwe amagwiritsidwa ntchito pokonza deta yopangidwa ndi sensa ndikuweruza ngati alamu iyenera kuyambitsidwa.
Choyambitsa ndi gawo lotulutsa la sensa ya alamu, pamene gawo lolamulira likuweruza kuti alamu iyenera kuyambitsidwa, idzatumiza chizindikiro kwa choyambitsa.
Chipangizo cha alamu ndi njira yomaliza ya alamu ya alamu, yomwe imatha kukhala buzzer, kuwala, mauthenga a foni yam'manja, foni, network, etc.
Mfundo yogwira ntchito ya alamu ndi: sensor nthawi zonse imayang'anitsitsa chilengedwe chozungulira ndikupanga deta.Kutengera ndi datayi, gawo lowongolera limaweruza ngati alamu ikufunika kuyambika.Pamene alamu iyenera kuyambitsidwa, gawo lolamulira limatumiza chizindikiro kwa choyambitsa, ndipo choyambitsacho chimatumiza chizindikiro ku chipangizo cha alamu, potsiriza kuzindikira ntchito ya alamu.
