Namuhla, sichitha isikhathi sethu esiningi singaphakathi endlini, futhi iqiniso liwukuthi Umoya wangaphakathi ungangcoliswa kakhulu kunomoya ongaphandle. Kungakhathaliseki ukuthi kuvela ezitofini ezishiswa ngokhuni, ukupheka, noma umoya ongenayo kahle, umoya ophefumulayo ogcwele izinhlayiya ezingabonakali ekugcineni uyalimaza. Ngenhlanhla, ngenxa ye-elekthronikhi evulekile, akusadingeki ukuchitha imali eningi emishinini yezimboni ukuze wazi kahle ukuthi siphefumula ini egumbini lethu lokuphumula.
Usebenzisa i- I-ESP32 njengobuchopho bephrojekthi, podemos montar una estación de monitoreo superpotente que no solo nos diga si el aire está «mal», sino que nos desglose la masa de partículas y los gases nocivos. Desde proyectos minimalistas hasta pantallas táctiles que parecen sacadas de una película de ciencia ficción, las posibilidades son enormes para quien quiera tomar las riendas de su salud ambiental ngaphandle kwezinkinga eziningikufana nendlela abanye abadalwa ngayo amarobhothi ahlelwe nge-ESP32.
Amaphrojekthi okubhekisela kuwo: i-Aura ne-AirGradient ONE
Uma ufuna ugqozi, kunezindlela ezimbili ezicacile kakhulu. Ngakolunye uhlangothi, sine-Project Aura, i-DIY powerhouse eyakha i- I-ESP32-S3 enesikrini sokuthinta se-IPS Into emangalisa kakhulu nge-Aura ukuthi isebenzisa inzwa ye-Sensirion SEN66, ekwazi ukukala i-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 elicishe libe lobuchwepheshe ezindaweni zemfundo noma emakhaya adinga kakhulu.
Ngakolunye uhlangothi lomgwaqo kukhona i-AirGradient ONE, okungenzeka ukuthi indinganiso yegolide yomthombo ovulekileIncane kakhulu futhi isebenzisa i-ESP32-C3 kanye nezinzwa ezithembeke kakhulu njenge-PMS5000 yezinhlayiya kanye ne-Senseair S8 ye-CO2. Ngenkathi i-Aura igxile ekubonisweni okukhulu kwendawo, i-AirGradient igxile ekubonisweni okukhulu kwendawo. ukunemba kwe-modular kanye nobululaokwenza kube inketho efanelekile kulabo abakhetha ukuhlanganisa yonke into kudeshibhodi yoMsizi Wasekhaya besebenzisa i-ESPHome noma ngisho Guqula i-Kindle endala ibe yideshibhodi ehlakaniphile.
Inhliziyo yokulinganisa: Izinzwa ze-laser vs. izinzwa ezishibhile
Aquí es donde mucha gente mete la pata. Hay sensores de polvo que cuestan cuatro duros (como el DSM501A) que básicamente miden cuánto se oscurece un haz de luz. Estos sirven para decir «estoy sucio», pero no te dan un dato real. En cambio, los sensores láser como el I-Sensirion SPS30 noma i-PMS5003 Basebenzisa ukuhlakazeka kokukhanya ukuze babale izinhlayiya ngazinye futhi babale isisindo sazo ngama-microgram nge-cubic meter (µg/m³).
Ukuba nenzwa ye-laser kukuvumela ukuthi uhlukanise phakathi intuthu esitovini (izinhlayiya eziningi ezicolekile kakhulu) kanye uthuli oluvela endaweni yokwakha (izinhlayiya ezimbalwa kodwa zinzima kakhulu). Lo mehluko ubalulekile ngoba i-PM2.5, okuyizinhlayiya eziyingozi kakhulu lapho zifika ku-alveoli yamaphaphu, ilinganiswa ngokunembe kakhulu kusetshenziswa lolu hlelo. bala ngobubanzi bosayizi.
Ukuhlanganiswa kobuchwepheshe kanye nokuphathwa kwamandla
Uma unquma ukuyakha, qaphela kakhulu ngogesi. Iphutha elivamile ukunika amandla inzwa kusuka ku-pin ye-3,3V ye-ESP32. Isibonelo, ifeni ye-SPS30 inesilinganiso samanje sokuqala esingaba ngu-800mA, okungadala inkinga. kubangela ukuthi i-microcontroller iqale kabusha njalo. Okungcono kakhulu, sebenzisa i-boost converter esethwe ku-5V enika amandla iphinikhodi ye-VIN ye-ESP32 kanye nenzwa ngqo, ukuqinisekisa ukuthi iyasebenza ukunikezwa kwamandla kwedivayisi.
Ukuze uvimbele idivayisi ukuthi ingangeni ku-reboot loop (brownout), kunconywa kakhulu ukuhlela i- ukuqala okuhleliweLokhu 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 ibhethri lika-18650 ukuthi lingabi nokwehla kwamandla kagesi ngokuzumayo. konakalisa ukuzinza kohlelo.
Isofthiwe, Amafu kanye Nezexwayiso Ezihlakaniphile
Ezingeni lekhodi, indlela ewusizo kakhulu ukusebenzisa i-MQTT ukuthumela idatha kumthengisi. Uma ungafuni ukubhekana namaseva akho, kunezinkundla ezifana ne-CircuitDigest Cloud ezikuvumela ukuthi udale amadeshibhodi asheshayo futhi, okuhle kunakho konke, Setha izexwayiso ezizenzakalelayo nge-WhatsAppCabanga ukuthi inkomba yekhwalithi yomoya idlula umkhawulo obalulekile bese uthola umlayezo efonini yakho ephathekayo ukuxwayisa ukuthi sekuyisikhathi sokuvula amafasitela.
Kubalulekile ukuvumelanisa izinkomba zekhwalithi yomoya (i-AQI) nemithetho yezwe lakini. Isibonelo, eChile, kusetshenziswa i-ICAP, lapho inani elingu-100 lihambisana nezinga lansuku zonke le-PM2.5. Ukusebenzisa isikali saseNdiya noma saseMelika akusizi ngalutho uma ufuna... Qhathanisa idatha yakho neziteshi ezisemthethweni yedolobha lakini. Ukudala umsebenzi wezibalo ohumusha ama-microgram ku-index yendawo, ngaphandle kwalokho ngeke kube yinto nje yokudlala. Ngalokhu, uzowuguqula ube yi- ithuluzi lokulinganisa eliwusizo.
Amathiphu awusizo okuhlanganisa i-capsulation
Ungafaki inzwa kunoma yiliphi ibhokisi elivalekile. I-SPS30 idinga ukuhamba komoya njalo, ngakho-ke indawo evalekile kumele ibe nayo izimbobo ezimbili eziklanywe kahleUkungena okukodwa kanye nokukhipha okukodwa. Uma ufaka imbobo eyodwa kuphela, umoya uzophinde ujikeleze futhi ukufundwa kwawo ngeke kube okunembile. Futhi, hlukanisa izinto zikagesi ezikhiqiza ukushisa (njenge-voltage regulator) ku-sensor, njengoba Umoya oshisayo ushintsha umswakama ohlobene futhi kungaphambukisa imiphumela phansi, ngendlela efanayo nendlela ukuhamba komoya kumafeni e-PC.
Kulabo abafuna ukwenza ngcono impilo yebhethri, isihluthulelo yilokhu imodi yokulala okujulileEsikhundleni sokulinganisa umzuzwana ngamunye, ungahlela i-ESP32 ukuthi ivuke njalo ngemizuzu eyishumi nanhlanu, uthathe isampula, uyilayishe efwini, bese ubuyela ebuthongweni. Ngaleli qhinga, ibhethri ebelizohlala amahora ambalwa lingahlala isikhathi eside kakhulu. ukusinda amasonto amaningana asikho isidingo sokushajwa 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.
