Fahimtar Aiki na Photocell da Muhimmancin Tsaro

Shi ne photocell kuma me ya ke mahimmanci don farko na garaji

Fotokil, wanda a known shi da maɓallin fotoelektrik, ya yi aiki kamar yanki mara inganci tsakanin mai aika da mai karɓar. Idan wani abu kashe wannan yanki, makoɗin gida either itace ko magana sannu, wanda ke taimakawa wajen zama ba ta hanyar nasara ga mutane, hayyuka ko abubuwan da aka barce a cikin hanyar sa. Tsarin Nazari na Iyali na Elekturun (NEISS) ya kara wasu abubuwa kuma ya fara da dubawa game da sakamako 20,000 daga makoɗin gida kowanne shekara. Wannan adadin ya nuna kyau meye ne ake buƙatar fotokil masu aiki don lafiyar gida.

Rolinta maɓallin fotokil a kula da nasara

An rage su a tsakanin 5 zuwa 6 inci sama dari, fotokil suna nigaba abubuwan da maɓallin limitin makini suna iya bude. Wannan teknulaji na maɓallin fotoelektrik tafiya a cikin sekondi daya lokacin da yanki ya kashe, kuma yana kare tsarin katattun. Maɓallin da suka dawo suna ƙasta 43% na nasaror makoɗin gida (Taron Lafiya na Gida 2022), kuma suna nuna yadda girma ne ingancin saukin mayar da su.

Yadda tsarin fotokil suna bin sharia'ar UL 325 na lafiya

Tsarin fasaha na zaman lafiya suna da alama ta UL 325, wacce ta richa:
