Lumelang bohle! Sengoloa sena se tla hlalosa ka botlalo le ho bonts'a mokhoa oa ho seta taolo ea remoutu ea module ea esp8266 u sebelisa sesebelisoa ka metsotso e 20 feela. Android ka protocol ea MQTT.

Ntle le moo, bokhoni ba ho amohela kapa ho romella data e hlokahalang ka nako efe kapa efe, ho sa tsotelehe sebaka sa hau, ho fana ka menyetla e mengata. Lihloohong tsa ka tse fetileng и ) Ke lekile ho nahana ka likhetho tse 'maloa tse theko e tlaase le tse batlang li le bonolo bakeng sa ho kenya tšebetsong taolo e hole ea li-microcontrollers ka Marang-rang. Leha ho le joalo, nako le lefats'e lohle ha li eme - tsoelo-pele e tsoela pele ho ea pele ka mokhoa o ke keng oa qojoa. Nakong ena e khuts'oane, mojule oa esp8266 o fumane botumo bo pharaletseng, boo, ka lebaka la theko ea eona e tlase le wi-fi e hahiloeng, e fetohile e 'ngoe ea likarolo tsa mantlha tsa Smart Home.
Hajoale, MQTT ke protocol e tsoetseng pele le e tsebahalang haholo ea phetisetso ea data lipakeng tsa lisebelisoa ka bomong ka har'a litsamaiso tsa Smart Home. E na le melemo e mengata ho feta liprothokholo tse ling:
- tšebeliso e tlase ea sephethephethe;

- ha e kenye mocha oa Inthanete;
- ho se be le tieho ea phetiso ea data;
- sistimi e bonolo ea lipeeletso tsa lihlooho;
Sena sohle se etsa hore ho khonehe ho beha leihlo le ho laola ka nako ea nnete. Leha ho le joalo, MQTT e hloka seva ea eona, e sebetsang e le mokena-lipakeng pakeng tsa bareki ba marang-rang. Ho na le mekhoa e 'meli ea ho iketsetsa seva ea hau kapa ho sebelisa litšebeletso tsa batho ba bang.
Sistimi ea taolo e hlalositsoeng e na le likarolo tse peli tse kholo: seva ea MQTT (hangata e le 'ngoe feela) le bareki, bao ho ka bang le ba bangata ho bona. Tabeng ea rona, bareki e tla ba sesebelisoa se sebetsang ho Android le mojule oa esp8266 ka boeona.
Algorithm ea ts'ebetso ea sistimi e tjena. Bareki ba hokahanya le seva mme hang ka mor'a hore ba hokahane, e mong le e mong oa bona o ingolisa ho lihlooho tseo a li thahasellang. Puisano eohle pakeng tsa bareki e feta ka seva, e fetisetsang data ho bareki ba bang ho latela lipeeletso tsa bona.
Seva ea MQTT.
Tabeng ea rona, re tla sebelisa tšebeletso e bonolo haholo e nang le moralo oa litefiso tsa mahala (Cute Cat) e tla koahela ka botlalo litlhoko tsa ho kenya ts'ebetsong tsamaiso e nyane ea lapeng e bohlale.
Ha re ingolise setšeng mme re fumane lintlha tse hlokahalang ho fihlella seva. Ha u lokisa bareki, u tlameha ho sebelisa Port e tloaelehileng (ntle le SSL le TLS).
Kopo e ho Android.
Kopo ea rona e tla sebetsa joalo ka phanele ea taolo bakeng sa microcontroller, hape e tla amohela le ho bonts'a tlhaiso-leseling eohle e fumanoeng ho tsoa ho esp8266.
Kopo e bitsoa hape ke moreki ea itokiselitseng mqtt ea nang le li-widget tse nyane tse sebetsang haholo. U ka shebella video bakeng sa lintlha tse ling mabapi le mokhoa oa ho sebelisa app.
Esp8266.
Module o khantšitsoe tikolohong ea lenaneo la Arduino, leha ho le joalo, ke batla ho hlokomela hore mojule o na le mathata le firmware liphetolelong tsa morao-rao tsa Arduino, ka hona ke khothaletsa ho sebelisa mofuta oa 1.6.4.
Mohlala, LED (8266 pins) le sensor ea mocheso ds5b18 (20 pins) li hokahane le esp2.
Kaha hoa hlokahala ho fumana data ho laola LED, ka mor'a ho hokela, esp e tlameha ho ingolisa ho "test / lead" sehlooho se ts'oanang, ho seng joalo data eohle e rometsoeng e tla feta ka microcontroller ea rona.
