Kodi mungatani kuti muchepetse "kusaoneka" kwa mpweya woipa m'madzi? Sensa ya CO₂ yosungunuka bwino kwambiri inapeza muyeso woyamba wolondola

Kodi tingayeze bwanji chinthu chosaoneka, chosakanikirana ndi chinthu chomwe sitingathe kukhala popanda? Funso ili lili pakati pa kugwiritsa ntchito chuma chathu chamtengo wapatali kwambiri: madzi. Kuti ndipeze yankho, ndinawerenga buku laukadaulo la chida china, sensa ya RD-WDCO2, yomwe imayesa carbon dioxide yosungunuka. Chomwe ndinapeza sichinali mndandanda wazinthu koma nkhani yaukadaulo wanzeru komanso zovuta zobisika. Nkhaniyi ikupereka zina mwazomwe zapezeka zodabwitsa komanso zodabwitsa zomwe zili m'bukuli, kusonyeza momwe zimakhalira zanzeru kuyang'anira chilengedwe chosaoneka chomwe chili mkati mwa dontho limodzi la madzi.

Sensa iyi "imawona" CO2 ndi kuwala kwa infrared.

M'malo mwa njira ya mankhwala kapena chowunikira cha thupi, sensa iyi imagwiritsa ntchito njira yodabwitsa yowunikira. Buku lophunzitsira limati ukadaulo wawo "umachokera pa mfundo ya NDIR infrared absorption," kotero zikutanthauza kuti amagwiritsa ntchito kuwala kwa infrared kosafalikira kuti adziwe ngati pali mamolekyu a CO2 ozungulira.

Kuti ikwaniritse kulondola kotereku, imafunika kutulutsa mtundu wina wa kuwala. Ili ndi "patented optical cavity, invented light source ndi dual-channel detector." Mtundu uwu wa kukhazikitsa ukhoza "kuzindikira reference reference of dual optical paths in the space," zomwe zikutanthauza kuti sensa nthawi zonse imatha kudzisunga yokha bwino ndikupereka ma reading olondola nthawi zonse, osati kutengera kuchuluka kwa mpweya womwe ulipo. Ndipo zotsatira zake ndi zabwino: kulondola ndi ±(20PPM+5% reading), ndipo nthawi yoyankha ndi yosakwana masekondi 20. Yankho labwino: kugwiritsa ntchito mtundu wina wa kuwala kuti muwerengere kuchuluka kwa mamolekyu a mpweya wopanda mtundu omwe amasungunuka m'madzi.

Ngakhale kuti ndi chida chamakono chowunikira, RD-WDCO2 yapangidwira dziko lenileni. Imatchula "kapangidwe kake kosavomerezeka kosalowa madzi" komwe kumatha kulekanitsidwa ndikutsukidwa mosavuta. Kukonza koyenera ndikofunikira pa chipangizo chomwe chingaikidwe m'matanki a nsomba kapena kuyang'anira madzi otuluka.

Yavomerezedwa mwalamulo kuti ili ndi IP68, zomwe zikutanthauza kuti ndi yotetezeka kwambiri ku fumbi ndipo imatha kumizidwa m'madzi kwa nthawi yayitali. Ndipo ndi umboni wina wosonyeza mphamvu zake chifukwa imatha kugwira ntchito pamitundu yonse ya kutentha kosiyanasiyana, kuyambira kuzizira mpaka madigiri 20 mpaka kutentha mpaka madigiri 60 Celsius, kotero ingakhale bwino mumtsinje wozizira kapena thanki yofunda yamafakitale. Nzeru za kapangidwe kake zafotokozedwa bwino ndi mzere wochokera m'bukuli.

Chipolopolocho ndi chopepuka komanso chosavuta kuyika pamalopo.

Ndipo imaphatikiza dongosolo lofewa lamkati ndi kunja kwamphamvu komwe anthu amatha kugwiritsa ntchito mosavuta. Izi zikutanthauza kuti amadziwa momwe zingakhalire zovuta kunja uko m'malo omwe chidziwitso chamtunduwu chili chofunikira kwambiri - monga m'mafamu a nsomba kapena kuonera zachilengedwe.

Chinthu chotsutsana kwambiri ndi zomwe ndinapeza chinali chakuti "Sensor ya CO2 Yosungunuka ndi Madzi" ingagwire ntchito ndi china chilichonse kupatula madzi. Buku lophunzitsira likuwonetsa kuti lili ndi mphamvu zina zabwino kwambiri zogwirira ntchito ziwiri zomwe zimapangitsa kuti ikhale yothandiza kwambiri kuposa momwe imatchulidwira.

Malinga ndi gwero, RD-WDCO2 ingagwiritsidwe ntchito kuyeza kuchuluka kwa CO2 yomwe yasungunuka m'madzi, ndipo ingagwiritsidwenso ntchito kuyang'anira kuchuluka kwa CO2 m'malo otentha komanso onyowa.

Ndipo kusinthasintha kumeneku kumapangitsa kuti ikhale chida chothandiza m'malo osiyanasiyana. Ingagwiritsidwe ntchito monga momwe idapangidwira "Kulima Zam'madzi" ndi "Kuwunika Ubwino wa Madzi", komanso ndi yabwino kwambiri pa "Kuwunika Zachilengedwe za Nyumba Zobiriwira za Ulimi" chifukwa chinyezi chambiri chingapangitse kuti zikhale zovuta kwa mitundu ina ya masensa a CO2.

4. Imalankhulana ndi chilankhulo chovuta cha digito

Sensa siigwira ntchito ngati singagawane zomwe yapeza. RD-WDCO2 sikuti imangowonetsa nambala, koma ikulankhula ndi makina osiyanasiyana pogwiritsa ntchito mitundu yosiyanasiyana ya makompyuta (zilankhulo za digito) kuti athe kudziwa zida zina kuchuluka kwa CO2 komwe kulipo. Imathandizira zizindikiro zosiyanasiyana zotulutsa ndi ma protocol monga RS485, UART, IIC.

Uwu si uthenga wamba. Kuti kompyuta iwerengedwe pogwiritsa ntchito njira yokhazikika ya MODBUS kudzera mu RS485, iyenera kutumiza chingwe cha lamulo mu mtundu wa hexadecimal. Mwachitsanzo, kuti ifunse sensa #32 kuti ione momwe CO2 ikuwerengera pakadali pano, wolandila angatumize uthengawu wokhala ndi code:

20 03 00 00 00 01 82 BB

Ndipo sensa idzayankha ndi uthenga wake wachinsinsi womwe uli ndi chidziwitso chofunikira:

20 03 02 01 AB 44 6C

Mu yankho ili, mfundo yofunika kwambiri ndi 01AB. Iyi ndi kuchuluka kwa CO2 mu mawonekedwe a hex, komwe ndi 427ppm mu ma decimal. Kukambirana kwachinsinsi kumeneku ndi komwe kumalumikizana kwambiri pakati pa dziko lotizungulira ndi makompyuta omwe amaliyang'anira, kusintha manambala osavuta kuchokera ku masensa kukhala chidziwitso chothandiza chomwe tingagwiritse ntchito.

Kutsiliza: Luso Lobisika mu Ukadaulo Watsiku ndi Tsiku

Kuyang'ana mozama buku la malangizo aukadaulo kukuwonetsa kuti ngakhale chomwe chikuwoneka ngati chipangizo chaching'ono ndi chodabwitsa cha mitundu yosiyanasiyana ya uinjiniya. Sensa imodzi yokhala ndi kuwala kwapamwamba kwambiri kowonera mpweya wosawoneka, kapangidwe kamphamvu kolimba kopirira zovuta, ndi malamulo ovuta a digito ogawana zomwe imapeza. Ndi chikumbutso champhamvu kuti kumbuyo kwa deta yonse yomwe ikuyenda padziko lonse lapansi, pali njira zabwino komanso zolimba zaukadaulo.

Ndipo zimenezo zimakupangitsani kuganiza kuti: ndi chiyani china chomwe zipangizo zodzikuzazi zikujambula mosaoneka, kuyang'anira machitidwe omwe timadalira popanda ife kudziwa?

Tikhozanso kupereka njira zosiyanasiyana zothetsera mavutowa

1. Chida chogwiritsira ntchito m'manja cha ubwino wa madzi okhala ndi magawo ambiri

2. Dongosolo loyandama la Buoy la ubwino wa madzi okhala ndi magawo ambiri

3. Burashi yoyeretsera yokha ya sensa yamadzi yokhala ndi magawo ambiri

4. Seti yonse ya ma seva ndi mapulogalamu opanda zingwe, imathandizira RS485 GPRS /4g/WIFI/LORA/LORAWAN

Kuti mudziwe zambiri zokhudza masensa amadzi
