Kulezi zinsuku, sichitha isikhathi sethu esiningi singaphakathi endlini, futhi iqiniso liwukuthi umoya wangaphakathi ungangcoliswa kakhulu kunomoya wangaphandle. Kungakhathaliseki ukuthi uvela ezitofini ezishiswa ngokhuni, ukupheka, noma umoya ongenayo kahle, umoya ophefumulayo ogcwele izinhlayiya ezingabonakali ekugcineni uyalimaza. Ngenhlanhla, ngenxa ye-elekthronikhi evulekile, asisadingi ukuchitha imali eningi emishinini yezimboni ukuze sazi kahle ukuthi siphefumula ini emakamelweni ethu okuhlala.
Sisebenzisa i- ESP32 njengobuchopho bephrojekthi , singakha isiteshi sokuqapha esinamandla kakhulu esingasitsheli nje kuphela ukuthi umoya "mubi," kodwa futhi sihlukanise inqwaba yezinhlayiya namagesi ayingozi. Kusukela kumaphrojekthi amancane kuya kuma-touchscreen abukeka sengathi avele ngqo kwi-movie yesayensi, amathuba makhulu kakhulu kunoma ubani ofuna ukulawula impilo yakhe yemvelo ngaphandle kwezinkinga eziningi , ngendlela amanye amarobhothi ahlelwe ngayo adalwa ngayo nge-ESP32.
Amaphrojekthi okubhekisela kuwo: i-Aura ne-AirGradient ONE
Uma ufuna ugqozi, kunezindlela ezimbili ezicacile kakhulu. Ngakolunye uhlangothi, kukhona i-Project Aura, i-DIY powerhouse esebenzisa i- ESP32-S3 enesikrini sokuthinta se-IPS esingu-4,3-intshi . Into emangalisayo kakhulu nge-Aura ukuthi isebenzisa inzwa ye-Sensirion SEN66, ekwazi ukulinganisa konke kusukela ku-PM1 kuya ku-PM10, i-CO2, kanye nama-volatile organic compounds (ama-VOC). Ikuvumela nokuthi ungeze inzwa ye-SFA30 formaldehyde, into cishe engekho omunye umuntu oyenzayo, okwenza kube ithuluzi eliseduze nobungcweti ezindaweni zemfundo noma emakhaya adinga kakhulu.
Ngakolunye uhlangothi lwe-spectrum kukhona i-AirGradient ONE, okungenzeka ukuthi iyindinganiso yegolide yomthombo ovulekile . Incane kakhulu futhi isebenzisa i-ESP32-C3 kanye nezinzwa ezithembeke kakhulu njenge-PMS5000 yezinhlayiya kanye ne-Senseair S8 ye-CO2. Ngenkathi i-Aura igxile ekubukeni okukhulu kwendawo, i-AirGradient ibeka phambili ukunemba kwe-modular kanye nobulula , okwenza kube ukukhetha okuhle kulabo abakhetha ukuhlanganisa konke kudeshibhodi ye-Home Assistant besebenzisa i-ESPHome noma ngisho nokuguqula i-Kindle endala ibe yideshibhodi ehlakaniphile.
Inhliziyo yokulinganisa: Izinzwa ze-laser vs. izinzwa ezishibhile
Yilapho abantu abaningi bephambuka khona. Kunezinzwa zothuli ezingabizi (njenge-DSM501A) ezilinganisa ukuthi ukukhanya kufihlwe kangakanani. Lezi zikutshela ukuthi "ngingcolile," kodwa azikuniki noma yiluphi ulwazi lwangempela. Ngokuphambene nalokho, izinzwa ze-laser ezifana ne- Sensirion SPS30 noma i-PMS5003 zisebenzisa ukusabalala kokukhanya ukuze zibale izinhlayiya ngazinye futhi zibale isisindo sazo ngama-microgram nge-cubic meter (µg/m³).
Ukuba nenzwa ye-laser kukuvumela ukuthi uhlukanise phakathi kwentuthu yesitofu (izinhlayiya eziningi ezithambile kakhulu) nothuli lokwakha (izinhlayiya ezimbalwa kodwa ezisindayo kakhulu). Lo mehluko ubalulekile ngoba i-PM2.5, okuyizinhlayiya eziyingozi kakhulu lapho zifika ku-alveoli yamaphaphu, zilinganiswa ngokunembe kakhulu kusetshenziswa lolu hlelo lokubala olusekelwe kusayizi.
Ukuhlanganiswa kobuchwepheshe kanye nokuphathwa kwamandla
Uma unquma ukuyakha, qaphela kakhulu ngogesi. Iphutha elivamile ukunika amandla inzwa kusuka kuphinikhodi engu-3,3V ye-ESP32. Isibonelo, ifeni ye-SPS30 inesilinganiso samanje sokuqala esingaba ngu-800mA, okungabangela ukuthi i-microcontroller iqale kabusha njalo . Okungcono kakhulu, kufanele usebenzise i-5V boost converter ukuze unike amandla iphinikhodi ye-VIN ye-ESP32 kanye nenzwa ngqo, ukuqinisekisa ukuthi idivayisi ihlinzeka ngogesi ofanele.
Ukuze uvimbele idivayisi ukuthi ingangeni ku-brownout loop, kunconywa kakhulu ukuhlela i- staggered boot . Lokhu kuhilela ukuvula isikrini kuqala, ukulinda imizuzwana embalwa, ukusebenzisa inzwa, bese uvula i-Wi-Fi kuphela. Ngaphezu kwalokho, ukunciphisa amandla okudlulisa i-Wi-Fi abe yi-15dBm kusiza ukuvimbela ukwehla kwamandla kagesi ngokuzumayo ebhethrini lika-18650 okungalimaza ukuzinza kohlelo.
Isofthiwe, Amafu kanye Nezexwayiso Ezihlakaniphile
Ezingeni lekhodi, indlela ewusizo kakhulu ukusebenzisa i-MQTT ukuthumela idatha kumthengisi. Uma ungafuni ukubhekana namaseva akho, amapulatifomu afana ne-CircuitDigest Cloud akuvumela ukuthi udale amadeshibhodi asheshayo futhi, okungcono kunakho konke, ulungiselele izexwayiso ezizenzakalelayo nge-WhatsApp . Cabanga ukuthi inkomba yekhwalithi yomoya idlula umkhawulo obalulekile bese uthola umlayezo efonini yakho ukuxwayisa ukuthi sekuyisikhathi sokuvula amafasitela.
Kubalulekile ukuvumelanisa i-Air Quality Index (AQI) nemithetho yezwe lakini. Isibonelo, iChile isebenzisa i-ICAP, lapho inani elingu-100 lihambisana nezinga lansuku zonke le-PM2.5. Ukusebenzisa isikali saseNdiya noma saseMelika akusizi ngalutho uma ufuna ukuqhathanisa idatha yakho neziteshi ezisemthethweni edolobheni lakini. Udinga ukudala umsebenzi wezibalo ohumusha ama-microgram ku-index yendawo; ngaphandle kwalokho, ngeke kube yinto engaphezu kwethoyizi. Ngokwenza lokhu, uzoyiguqula ibe ithuluzi lokulinganisa eliwusizo.
Amathiphu awusizo okuhlanganisa i-capsulation
Ungafaki inzwa kunoma yiliphi ibhokisi elivalekile. I-SPS30 idinga ukugeleza komoya okuqhubekayo, ngakho-ke indawo evalekile kumele ibe nezimbobo ezimbili eziklanywe kahle : eyodwa yokungenisa kanye nenye yokukhipha umoya. Uma usebenzisa imbobo eyodwa kuphela, umoya uzophinde ujikelezwe, futhi ukufundwa ngeke kube okunembile. Futhi, hlukanisa noma yimaphi ama-elekthronikhi akhiqiza ukushisa (njenge-voltage regulator) ku-sensor, njengoba umoya oshisayo ushintsha umswakama ohlobene futhi ungaguqula imiphumela ibe phansi, ngendlela efanayo nendlela ukugeleza komoya okuphathwa ngayo kumafeni e-PC.
Kulabo abafuna ukwenza ngcono impilo yebhethri, isihluthulelo imodi yokulala ngokujulile . Esikhundleni sokulinganisa umzuzwana ngamunye, ungahlela i-ESP32 ukuthi ivuke njalo ngemizuzu eyishumi nanhlanu, uthathe isampula, uyilayishe efwini, bese ubuyela ebuthongweni. Ngaleli qhinga, ibhethri elivame ukuhlala amahora ambalwa lingahlala amasonto amaningana ngaphandle kokudinga ukushajwa kabusha.
Ukuhlanganisa i-ESP32 nezinzwa ze-laser ezisezingeni eliphezulu kukuvumela ukuthi uguqule isikhala sibe yindawo eqashwe ngochwepheshe. Kungakhathaliseki ukuthi ngamandla okubona e-Project Aura, ubulula be-AirGradient, noma ukusetha ngokwezifiso ngezixwayiso ze-WhatsApp kanye nokwenza ngcono amandla, isihluthulelo ukuguqula idatha engabonakali ibe yizenzo eziqondile zokuthuthukisa impilo yokuphefumula ekhaya.
