Malangizo 4 Maupangiri Pakugula Kutentha & Chinyezi Sensor

Zowunikira kutentha ndi chinyezi zimatha kupezeka kulikonse m'moyo. Masensawa amatha kuyeza mpweya wa madzi mumpweya ndi kutentha kozungulira. Koma zimagwira ntchito bwanji, ndipo mitundu yawo ndi yotani?

1. Kodi Ndi ChiyaniZowona za Kutentha ndi Chinyezi?

Masensawa amapangidwa kuti azigwiritsidwa ntchito zosiyanasiyana ndipo amagwiritsidwa ntchito poyeza chinyezi ndi kutentha kwa chilengedwe.

Amachita izi popeza kuchuluka kwa nthunzi yamadzi yomwe imapezeka mumlengalenga wozungulira sensor. Chinyezi mu gasi chikhoza kukhala chosakaniza cha zinthu zosiyanasiyana, kuphatikizapo nayitrogeni, nthunzi wamadzi, argon, ndi zina zotero.

Popeza chinyezi chikhoza kukhala ndi mphamvu yaikulu pazochitika zosiyanasiyana zamoyo, mankhwala ndi zakuthupi, ziyenera kuyesedwa ndikuyendetsedwa m'mafakitale osiyanasiyana choncho, masensawa amafunikira kuti atithandize.

2. Kutentha ndi chinyezi masensa

Kodi masensa a kutentha ndi chinyezi amagwira ntchito bwanji?

Pali njira ziwiri zosiyana zomwe masensa a kutentha ndi chinyezi amasonkhanitsira deta ndikuyesa chinyezi ndi kutentha.

1. Muyeso umodzichinyezi chachibale (chomwe chimadziwikanso kuti RH)

2. Winayoamayesa chinyezi chonse (chomwe chimatchedwanso AH).

Akhozanso kugawidwa malinga ndi kukula kwawo. Masensa ang'onoang'ono amagwiritsidwa ntchito pazigawo zing'onozing'ono, pamene masensa akuluakulu amagwiritsidwa ntchito popanga mafakitale.

Ena mwa masensawa amalumikizidwa ndi microcontroller kuti ayese pompopompo deta yoyenera. Masensa awa ali ndi capacitive humidity sensing element ndi thermistor yozindikira kutentha komwe kuli. Thesensor chinyezielement (capacitor) ili ndi maelekitirodi awiri ndipo gawo losunga chinyezi limagwiritsidwa ntchito ngati dielectric pakati pa maelekitirodi awiriwa. Nthawi zonse mulingo wa chinyezi ukasintha, kuchuluka kwa capacitance kumasintha moyenera. Pali IC yophatikizika mkati mwa selo yomwe imalandira deta yoyezera ndikuyendetsa zotsutsana zomwe zimasintha chifukwa cha kusintha kwa chinyezi ndikusintha deta kukhala mawonekedwe a digito kwa owerenga.

Kufotokozera kosavuta ndikuti masensawa amagwiritsa ntchito choyezera kutentha koyipa kuti athe kuyeza kutentha. Kutentha kozungulira kukakwera, chinthucho chimapangitsa kuti kukana kwake kuchepe.

Kuphatikiza apo,pali zoyezera kutentha ndi chinyezi zokhala ndi zowonetsera zomwe zimapangidwira kupereka malipoti owoneka bwino a chinyezi ndi kutentha ndikupanga chidziwitso chabwinoko kwa wogwiritsa ntchito pogwiritsa ntchito masensa oterewa. Mwachitsanzo, kutentha kwa 802c ndi 802p ndi chinyezi chokhala ndi chiwonetsero, masensa ndi abwino kwambiri mukakhala kunja ndikufunika kuyang'anira kutentha ndi chinyezi cha malo. Amakhalanso ndi kulondola kwakukulu!

3. Kulondola kwamafakitale kutentha ndi chinyezi masensa

Kulondola kwa mitundu yosiyanasiyana ya kutentha ndi chinyezi kumasiyanasiyana.

Mwachitsanzo, makina a HT802 amtundu wa kutentha ndi chinyezi ali ndi ± 2% molondola ndipo amatha kuyeza mpaka 80% chinyezi.

Ichi ndichifukwa chake masensa apamwamba kwambiri amagwiritsidwa ntchito kwa mafakitale omwe amakhudzidwa kwambiri kuti asunge kutentha ndi chinyezi pamlingo wina, popeza amapereka deta yolondola komanso yodalirika.

Mwachitsanzo, magawo a zanyengo ndi sayansi amafunikira masensa okhala ndi muyeso wa chinyezi kuchokera paziro mpaka 100% RH. Madera ena safuna kuchuluka kwathunthu kuti agwiritse ntchito. Muyeneranso kudziwa kuti masensa okhala ndi milingo yayikulu nthawi zambiri amawononga ndalama zambiri kuposa masensa okhala ndi miyeso yotsika.

TheMtengo wa HT802Sensor yotsatizana ya kutentha ndi chinyezi yomwe tatchula kale imakhala yokwanira pazogwiritsa ntchito zosiyanasiyana ndipo imawononga ndalama zochepa kuposa zomwe zimagwiritsidwa ntchito pazovuta kwambiri. Ngati mukufuna kulondola kwambiri koma mulibe bajeti yayikulu.

4. Chinyezi ndi kutentha Sensor Mapulogalamu

Monga tafotokozera pamwambapa, masensa awa amapezeka pazida zambiri, ndipo ali ndi ntchito zosiyanasiyana!

Atha kuthandiza ngakhale odwala omwe ali ndi vuto la kupuma powalola kusunga chinyezi ndi kutentha kwa malowo pamlingo woyenera.

1. Poneneratu za nyengo, masiteshoni anyengo amagwiritsanso ntchito masensa amenewa.

2. Atha kugwiritsidwa ntchito potenthetsa ndi mpweya wabwino, komanso makina owongolera mpweya.

3. Masensa awa atha kugwiritsidwanso ntchito m'malo obiriwira pomwe chinyezi chiyenera kuyang'aniridwa pafupipafupi.

4. Malo osungiramo zinthu zakale angapindulenso nawo, chifukwa awa ndi malo omwe zinthu zakale ndi zinthu ziyenera kusungidwa pansi pa mikhalidwe ina.

Pomaliza, ndingasankhe bwanji Sensor yoyenera ya Kutentha ndi Chinyezi?

Pali zofunikira zomwe mungafunike kuziganizira posankha mankhwalawa. Izi zikuphatikizapo:

a. Kulondola;

b.Kubwerezabwereza.

c.Kukhazikika kwanthawi yayitali;

d.Kusinthana;

e.Kutha kuchira kuchokera ku condensation;

f.Kukana zonyansa zakuthupi ndi mankhwala;

HENGKO's zosunthika, mkulu-ntchito mafakitale kutentha ndi chinyezi masensa ndi oyenera malo ankhanza mafakitale.

Chogulitsacho chimatenga masensa apamwamba kwambiri a RHT omwe ali olondola kwambiri komanso mphamvu zotsutsana ndi kusokoneza, kuwonetsetsa kuti muyeso ukuyenda bwino.

Masensa a kutentha kwa Industrial ndi chinyezi amakhala ndi kukhazikika kwanthawi yayitali, kutsika pang'ono, kukana kuipitsidwa ndi mankhwala, komanso kubwereza kopambana.

Muli Ndi Mafunso Ndimakonda Kudziwa Zambiri Zakuwunikira Chinyezi Panyengo Yovuta Kwambiri, Chonde Khalani Omasuka Lumikizanani Nafe Tsopano.
