Lub qhov rooj hloov lub qhov rooj yog ib yam uas cov neeg tsis paub kov tshaj plaws. Thiab nrog covid 19 kev kis thoob qhov txhia chaw dhau los ua qhov teeb meem loj, tswj kev tu cev zoo tau dhau los ua qhov tseem ceeb tshaj plaws niaj hnub no.
Yog li hauv cov lus qhia no, kuv yuav qhia koj txoj hauv kev yooj yim los hloov kho koj lub tswb qhov rooj uas twb muaj lawm mus rau qhov kov-tsawg dua yam tsis tau siv Arduino. Yog! Tsis muaj Arduino. Tsis tas li nws siv cov khoom siv tsawg heev yog li nws yuav yooj yim los tsim. Nco ntsoov lub xauv tam sim no hauv ntau lub tebchaws, Kuv tau siv cov khoom txwv kom koj tuaj yeem tsim qhov no tau yooj yim. Kuv xav qhia koj thawj zaug saib cov vis dis aus uas kuv tau piav qhia lub tsev txheej txheem kom meej.
Khoom siv
IR qhov sib thooj sensor
BC547 lossis lwm yam NPN transistor
Siv 5v relay
Qee cov xov hlau
Lub roj teeb 5v/Lub zog hloov pauv (Koj lub xov tooj lub xov tooj qub yuav tsum tau ua txoj haujlwm tiav!)
Kauj Ruam 1: Yuav Ua Li Cas Qhov Sib Thooj Sensor Ua Haujlwm
Rau qhov kev tsim no, koj yuav tsum paub ib qho me me txog qhov ntsuas no. Muaj ob lub qhov muag teev nyob rau ntawm xub ntiag. Thaum ib yam khoom los rau pem hauv ntej ntawm cov no, lub ntsuas pom nws thiab tso tawm 3.3v digital teeb liab los ntawm nws D0 tus pin nyob tom qab. Yog tias koj xav kho nws qhov rhiab heev, koj tuaj yeem siv tus ntsia hlau tsav thiab tig lub onboard potentiometer kom txog thaum koj tau txais qhov xav tau ntau yam.
Lub phiaj xwm yog siv 3.3v cov teeb liab los ntawm D0 los ua kom muaj kev sib txuas uas ua rau lub qhov rooj hloov mus.
Kauj ruam 2: Relay Terminals
Cov relay muaj 5 tus pin. Ob rau cov tswv yim, 5v hauv qhov no. Tom qab ntawd ob qho ntxiv rau cov zis. C.m os tus pin yog ib txwm rau cov zis. Tom qab ntawd muaj NC lossis ib txwm kaw thiab TSIS muaj lossis nquag qhib pins. Txij li thaum lub Circuit Court yuav tsum tsuas yog tshwm sim thaum qhov sib thooj sensor pom koj txhais tes, peb yuav tsum txuas qhov tso tawm ntawm NO thiab COM pins.
Kauj Ruam 3: Tus Kheej Transistor
Lub transistor muaj 3 tus pin. Collector, puag thiab emitter. Tshwj tsis yog tias koj xav kom muaj chav kawm hluav taws xob ntawm no, qhov no yog txhua yam koj xav paub txog transistor rau tam sim no.
Kauj Ruam 4: Ua Kev Sib Txuas
Okay, tsis muaj ntaus nyob ib ncig ntawm lub hav txwv yeem. Kuv yuav ncaj nraim mus.
5v tus pin ntawm lub sensor mus rau qhov zoo 5v los ntawm cov khoom siv hluav taws xob.
GND ntawm lub sensor mus rau transistor tus emitter.
D0 mus rau transistor lub hauv paus.
Transistor tus neeg sau mus rau ib tus pin nkag ntawm kev xa tawm.
Transistor tus emitter tseem mus rau qhov tsis zoo ntawm lub zog hluav taws xob
Lwm tus pin nkag ntawm kev xa mus mus rau qhov zoo 5v los ntawm lub hwj chim.
Qhov tso tawm ntawm kev xa tawm (COM thiab TSIS MUAJ) yuav tom qab txuas nrog lub qhov rooj tswb tswb uas twb muaj lawm
Kauj Ruam 5: Ua Lub Hauv Paus Ntsuab
Tom qab ntawd kuv tau kaw txhua yam ntawm daim duab los qhia thiab teeb tsa cov xov hlau nrog daim kab xev hluav taws xob.
Tom qab ntawd kuv khoov lub qhov muag teeb rau pem hauv ntej. Yog li nws tuaj yeem ntsia tau yooj yim. Kuv txiav ob daim duab ib nrab ntawm cov duab los qhia thiab daig rau saum thiab hauv qab ntawm lub hauv paus. Kuv tau ua tus thais hauv ib ntawm lawv kom dhau lub roj teeb them hlau xaim hla
Kuv txiav tawm ib daim ntawv ntawm daim ntawv dub thiab ua lub qhov rau lub ntsuas kom pom los ntawm. Siv ob daim kab xev ua npuas ncauj, tom qab ntawd kuv tau kaw lub sensor tom qab lub qhov kom ntseeg tau tias muaj qhov chaw txaus nyob ib puag ncig lub qhov muag teeb kom nws thiaj li tsis yuam kev. Tom qab ntawd kuv tau daig daim ntawv dub nyob ib ncig ntawm daim ib nrab ib ncig nrog qee cov nplaum. Peb qhov kov tsis siv neeg tau npaj tiav!
Kauj Ruam 6: Txuas mus rau Hloov
Feem ntau, Lub Tswb Tswb tsis siv los ntawm lub hauv paus, yog li nws yuav tsum muaj kev nyab xeeb. Tab sis tsuas yog kom muaj kev nyab xeeb dua, tua MCB ua ntej cuam tshuam nrog cov xov hluav taws xob. Txawm hais tias nws nyab xeeb los ntawm no, ua raws li koj tus kheej txoj kev pheej hmoo. Hnav hnab looj tes, khau thiab ris tsho tiv thaiv yog tias ua tau.
Ua ntej tshaj, kuv rub qhib lub hau npog sab nrauv ntawm lub rooj hloov khoom. Tom qab ntawd kuv tshem cov ntsia hlau thiab tshem tawm lub rooj tsavxwm. Koj tuaj yeem pom ob lub xov hlau txuas nrog rau qhov hloov. Peb yuav tsum txuas ob lub xov hlau los ntawm kev xa tawm mus rau cov kab no. Tsis txhob tshem cov xov hlau uas twb muaj lawm lossis tsis muaj dab tsi yuav ua haujlwm.
Kauj Ruam 7: Npaj Ua Kov-tsawg
Tom qab txuas, kuv txuas lub rooj tsavxwm rov qab, thiab kaw qhov kov tsis tau ib sab nws siv daim kab xev ob tog. Koj tuaj yeem siv cov nplaum lossis cov ntsia hlau yog tias koj xav tau qhov txuas ntxiv mus tas li. Tom qab ntawd kuv tau hloov MCB rov qab thiab pib ntsuas.
Tam sim no yog tias peb nqa peb txhais tes los ze rau lub ntsuas cua, lub pob qhov rooj nrov nrov. Zoo kawg. Nws muaj ntau yam zoo ib yam nkaus. Qhov zoo yog tias peb tseem tuaj yeem siv lub cev hloov pauv uas twb muaj lawm. Tus qauv tsim zoo nkauj zoo nkauj thiab niaj hnub no. Vam tias koj txaus siab rau txoj haujlwm thiab yuav txaus siab ua nws ntau dua. Ib zaug ntxiv, kuv xav kom koj saib cov vis dis aus kom nkag siab meej.
