Bayan shekaru da yawa na aiki mai amfani, an yanke shawarar kawo wa jama'a samfurinmu na farko don sarrafa yanayi a cikin gida mai wayo - na'ura mai wayo don sarrafa benaye masu zafi.
Menene wannan na'urar?
Wannan shi ne mai wayo mai zafi don kowane bene mai zafi na lantarki har zuwa 3kW. Ana sarrafa shi ta hanyar aikace-aikace, shafin yanar gizon, HTTP, MQTT, don haka ana iya haɗa shi cikin sauƙi a cikin duk tsarin gida mai wayo. Za mu haɓaka plugins don mafi mashahuri.
Kuna iya sarrafa ba kawai bene mai zafi na lantarki ba, har ma da shugaban thermal don bene mai zafi na ruwa, tukunyar jirgi ko sauna na lantarki. Hakanan, ta amfani da nrf, ma'aunin zafi da sanyio zai iya sadarwa tare da na'urori daban-daban. Kusan duk na'urori masu auna yanayin yanayi a halin yanzu suna ci gaba. Tun da na'urar ta dogara ne akan ESP, mun yanke shawarar cewa ba zai dace ba a cire zaɓuɓɓukan gyare-gyare daga masu amfani. Don haka, za mu sanya shi don mai amfani zai iya canza na'urar zuwa yanayin haɓakawa kuma shigar da wasu firmware, misali, tare da goyan bayan HomeKit ko ayyukan ɓangare na uku.
*bayan shigar da firmware na ɓangare na uku tare da goyan bayan HomeKit ko wasu mashahuran ayyukan, komawa zuwa na asali ba zai yiwu ta hanyar OTA (Over-the-Air).
Matsalolin da muka fuskanta
A ce babu kowa zai zama wawa. Zan yi kokarin bayyana matsalolin da suka fi wahala da suka taso da kuma yadda muka magance su.
Gidajen na'urar ya kasance kalubale. Duka dangane da farashin albarkatun ƙasa da farashin lokaci (an haɓaka su kusan shekara guda).
Akwai zaɓuɓɓuka da yawa akan kasuwa. Kuma mafi mashahuri shine 3D bugu. Bari mu gane shi:
Classic 3D bugu. Ingancin yana barin abubuwa da yawa da ake so, kamar yadda saurin samarwa yake. Mun yi amfani da bugu na 3D don samfura, amma bai dace da samarwa ba.
Photopolymer 3D printer. Anan ingancin ya fi kyau, amma tasirin farashin ya shigo cikin wasa. Samfuran da aka buga akan firinta mai kama da ita sun kai kusan 4000 rubles, kuma wannan bangare ne na jiki daga cikin biyun. Kuna iya siyan firinta na kanku, wanda zai rage farashin, amma har yanzu farashin zai kasance na astronomical, kuma saurin zai zama mara gamsarwa.
Simintin siliki. Mun dauki wannan zaɓi mafi kyau. Ingancin yana da kyau, farashin yana da yawa, amma ba mahimmanci ba. Har ma an ba da umarnin rukunin farko na kararraki 20 don gwajin filin.
Amma dama ta canza komai. Wata maraice, na bazata a cikin hira na ciki don masu haɓakawa cewa akwai matsala tare da lokuta, farashin ya yi yawa. Kuma washegari, wani abokin aiki ya rubuta a cikin saƙo na sirri cewa abokin abokinsa yana da TPA (na'urar thermoplastic). Kuma a mataki na farko zaka iya yin mold don shi. Wannan sakon ya canza komai!
Tun da farko na yi tunanin yin amfani da injin ɗin allura, amma abin da ya hana ni ba ma buƙatar yin odar batch na aƙalla guda 5000 ba (ko da yake idan kun gwada, za ku iya samun ƙasa ta hanyar Sinanci). Farashin mold ya dakatar da ni. Kimanin $5000. Ban shirya biyan wannan adadin lokaci guda ba. Adadin samfurin ta hanyar sabon abokin aikinmu ba na ilimin taurari bane, ya bambanta kusan $2000-$2500. Bugu da kari, ya yarda ya gana da mu kuma mun amince za a biya a kan kari. Don haka an warware matsalar da ƙwanƙwasa.
Na biyu kuma ba ƙaramin mahimmancin wahala da muka fuskanta shine hardware.
Ba za a iya ƙididdige adadin sake fasalin kayan aikin ba. Bisa ga ƙididdiga masu ra'ayin mazan jiya, zaɓin da aka gabatar shine na bakwai, ba tare da ƙidayar matsakaici ba. A ciki mun yi ƙoƙarin warware duk gazawar da aka gano yayin aikin gwaji.
Don haka, a baya na yi imani cewa babu buƙatar mai kula da kayan aiki. Yanzu, ba tare da shi ba, na'urar ba za ta shiga cikin samarwa ba: saboda girman dandali da muka zaɓa.
Wani shigarwar analog zuwa ESP. A baya na yi tunanin cewa kowane fil ɗin ESP na duniya ne. Amma ESP yana da fil ɗin analog ɗaya kawai. Na koyi wannan a aikace, wanda ya kai ga sake yin aiki da sake yin oda da allunan da’ira da aka buga.

The penultimate version of buga kewaye allon, inda dole ne mu gaggawa warware matsaloli tare da analog fil
Dangane da manhaja, akwai kuma matsaloli da yawa.
Misali, ESP yana faɗuwa lokaci-lokaci. Ko da yake ping ɗin yana zuwa gare shi, shafin baya buɗewa. Akwai mafita ɗaya kawai - sake rubuta ɗakin karatu. Wataƙila akwai wasu, amma duk waɗanda muka gwada ba su yi aiki ba.
Matsala ta biyu mai mahimmanci, mai ban mamaki, ita ce adadin buƙatun ga ESP lokacin buɗe shafi. Amfani da GET ko ajax, mun fuskanci gaskiyar cewa adadin buƙatun ya zama babba. Saboda wannan, ESP ya nuna halin rashin tabbas, zai iya sake yin aiki kawai ko aiwatar da buƙatar na daƙiƙa da yawa. Maganin shine canza zuwa kwasfan yanar gizo. Bayan wannan, adadin buƙatun ya ragu sosai.
Matsala ta uku ita ce hanyar sadarwa ta yanar gizo. Ƙarin bayani game da shi zai kasance a cikin wani labarin dabam wanda za a buga daga baya.
A yanzu zan faɗi cewa mafi kyawun zaɓi a yanzu shine amfani da VUE.JS.
Wannan tsarin shine mafi dacewa da duk abubuwan da muka gwada.
Za a iya duba zaɓuɓɓukan mu'amala a hanyoyin haɗin da ke ƙasa.
Zama thermostat
Bayan mun shawo kan dukkan matsalolin, mun kai ga wannan sakamakon:
Ginin
Thermostat ya ƙunshi alluna uku (modules):
- Manajan;
